I'm pulling Twitter data via their API and one of the tweets has a special character the right apostrophe and I keep getting an error saying that Python can't map or character map the character. I've looked all over the Internet, but I have yet to find a solution for this issue. I just want to replace that character with either an apostrophe that Python will recognize, or an empty string essentially removing it.

I'm using Python 3. Any input on how to fix this problem? It may seem simple, but I'm a newbie at Python. Edit: Here is the function I'm using to try to filter out the unicode characters that throw errors.

Firstly, you are passing the wrong code point to chr. So you need to do either:. Secondly, the reason you are getting the error is because some other part of your program probably the database backend is trying to encode unicode strings using some encoding other than UTF It's hard to be more precise about this, because you did not include the full traceback in your question.

Anyway, the correct way to deal with this issue is to ensure all parts of your program and especially the database use UTF If you do that, you won't have to mess about replacing characters anymore.

Can you show a sample of the data and your code? Thanks for adding a little more info, but without knowing how you got the data or exactly which line is generating the error it's hard to help. Active Oldest Votes. There seem to be two problems with your program. Funny, I was thinking about a similar solution last night. Haven't been able to try it yet though. I tried your first suggestion and all issues are resolved.

Do you have to import a package for the function 'unicode '? No you don't. It's built in. Python does not seem to recognize it.

I am trying to learn python and couldn't figure out how to translate the following perl script to python:. The script just changes unicode umlauts to alternative ascii output.

So the complete output is in ascii. I would be grateful for any hints. In case you are using python 3 strings are by default unicode and you dont' need to encode it if it contains non-ASCII characters or even a non-Latin characters.

So the solution will look as follow:. You could try unidecode to convert Unicode into ascii instead of writing manual regular expressions.

It is a Python port of Text::Unidecode Perl module:. You can change the decode language to whatever you need.

You may want a simple function to reduce length of a single implementation. Learn more. How to replace unicode characters by ascii characters in Python perl script given? Ask Question. Asked 10 years, 5 months ago. Active 7 months ago. Viewed 32k times.

And this one replaces non-ASCII characters with the amount of spaces as per the amount of bytes in the character code point i. Of the myriad of similar SO questionsnone address character replacement as opposed to strippingand additionally address all non-ascii characters not a specific character.

Your ''. For you the get the most alike representation of your original string I recommend the unidecode module :. But note you will still have a problem if your string contains decomposed Unicode characters separate character and combining accent marks, for example :.

If the replacement character can be '? As a native and efficient approach, you don't need to use ord or any loop over the characters. Just encode with ascii and ignore the errors. Potentially for a different question, but I'm providing my version of Alvero's answer using unidecode. I want to do a "regular" strip on my strings, i.

Before posting here I resarched the subject of unicode replace, but got nowhere. I am using Python 3 version of Autokey, with which I want to run a script to clean up scanned text.

Please see sample text below the code. Can someone in the know suggest what I am missing? But neither in their losses nor in their gains have all strains evolved to the same extent. Some races have lost the skin pigment, but others have made little progress in this direction. We are getting rid of our body coat of hair, but the Akkas of the Upper Nile and special smaller strains have a very hairy body, and so appendix and tail coccyx show variations that run in families.

Likewise in the acquisition of mental traits, whole races differ in their ability to speak, to count, to foresee. The Ethiopian has no more need for thrift than the tropical monkey and has not acquired it. It takes the string, page generates a new one with the replacement completed, but then nothing happens with that generated string.

After you capture the result of the replacement, you'd then need to do a clipboard. I don't see a definition of that variable and I'm not familiar with Autokey but I imagine an API exists for what you want.

Feel like you're not getting the answers you want? Pro-tip - there's an inverse correlation between the number of lines of code posted and my enthusiasm for helping with a question :.Unicode is a computing standard for the consistent encoding symbols. It was created in Encoding takes symbol from table, and tells font what should be painted. But computer can understand binary code only.

So, encoding is used number 1 or 0 to represent characters. Like In Morse code dots and dashes represents letters and digits. Each unit 1 or 0 is calling bit. Most known and often used coding is UTF It needs 1 or 4 bytes to represent each symbol. If you want to know number of some Unicode symbol, you may found it in a table. Or paste it to the search string. On the symbol page you can see how it's looking like in different fonts and operating systems.

You may copy this and paste it to Word or Facebook. Also, there are several character sets on this site for more comfortable coping. Different part of the Unicode table includes a lot characters of different languages. Almost all writing systems using these days represent. LatinArabicCyrillichieroglyphs, pictographic. Letters, digits, punctuation.

Also Unicode standard covers a lot of dead scripts abugidas, syllabaries with the historical purpose. Many other symbols, which are not belong specific writing system coded too. It's arrows, stars, control characters etc. All humanity needs to produce high-quality text. In June was released version 8. More than thousands characters coded for now.

The Consortium does not create new symbols, just add often used. Faces emoji included because it was often used by Japanese mobile operators. But some units does not containing a matter of principle. There are not trademarks in Unicode table, even Windows flag or registered trademark of apple. Read more. Language English. Popular character sets See all. Unicode number:. The Unicode standard Unicode is a computing standard for the consistent encoding symbols. Read more Accept.Then you encode the result to pass it to SetField.

File is now correctly encoded as UTF-8 and Unicode characters display correctly. There are different ways to define strings in Python:. UTF-8 is a way of decoding for unicode. Summary In this tutorial of Python Exampleswe learned how to write a string to a text file, with the help of example programs.

Previous: Write a Python program to replace maximum 2 occurrences of space, comma, or dot with a colon. If you talk to a network now, we have to understand. Changes in the Unicode Character Database.

This function isn't necessary in Python 3, where strings are Unicode by default. A number specifying how many occurrences of the old value you want to replace. Ask Question Asked 3 years, 11 months ago. When the specification for the Java language was created, the Unicode standard was accepted and the char primitive was defined as a bit data type, with characters in the hexadecimal range from 0x to 0xFFFF.

If not provided, the replace Python method will replace all occurrences. The corresponding output in the DB table is coming to a single character for all the values. The end result will be one long unbroken line 2 Given a string altered as in step 1, "decode" it back to the original string. For more details, see this blog post.

Below is the ASCII character table and this includes descriptions of the first 32 non-printing characters. Normally, CSV files use a comma to separate each specific data value.

Re: python: how do I remove the first and last character from a variable? DonVla's regex does a pretty reasonable job - you'd do well to get into re syntax.

For all characters with an odd right-to-left embedding level, those of type L, EN or AN go up one level. Strip can be used for more than whitespace. I cant do anything on client side because server sends it that way.

Yet today, all is fine, no problems whatsoever.Applications are often internationalized to display messages and output in a variety of user-selectable languages; the same program might need to output an error message in English, French, Japanese, Hebrew, or Russian. Web content can be written in any of these languages and can also include a variety of emoji symbols. The Unicode specifications are continually revised and updated to add new languages and symbols.

A character is the smallest possible component of a text. The Unicode standard describes how characters are represented by code points. A code point value is an integer in the range 0 to 0x10FFFF about 1.

The Unicode standard contains a lot of tables listing characters and their corresponding code points:. In informal contexts, this distinction between code points and characters will sometimes be forgotten.

The glyph for an uppercase A, for example, is two diagonal strokes and a horizontal stroke, though the exact details will depend on the font being used. To summarize the previous section: a Unicode string is a sequence of code points, which are numbers from 0 through 0x10FFFF 1, decimal. This sequence of code points needs to be represented in memory as a set of code unitsand code units are then mapped to 8-bit bytes.

The rules for translating a Unicode string into a sequence of bytes are called a character encodingor just an encoding. In most texts, the majority of the code points are less thanor less thanso a lot of space is occupied by 0x00 bytes.

UTF-8 is one of the most commonly used encodings, and Python often defaults to using it. UTF-8 uses the following rules:. UTF-8 is fairly compact; the majority of commonly used characters can be represented with one or two bytes. UTF-8 is a byte oriented encoding. The encoding specifies that each character is represented by a specific sequence of one or more bytes. This avoids the byte-ordering issues that can occur with integer and word oriented encodings, like UTF and UTF, where the sequence of bytes varies depending on the hardware on which the string was encoded.

Be prepared for some difficult reading.

A chronology of the origin and development of Unicode is also available on the site. To help understand the standard, Jukka Korpela has written an introductory guide to reading the Unicode character tables.

Another good introductory article was written by Joel Spolsky. Since Python 3. The default encoding for Python source code is UTF-8, so you can simply include a Unicode character in a string literal:. Depending on your system, you may see the actual capital-delta glyph instead of a u escape. In addition, one can create a string using the decode method of bytes. This method takes an encoding argument, such as UTF-8and optionally an errors argument.

The following examples show the differences:. Python comes with roughly different encodings; see the Python Library Reference at Standard Encodings for a list.

One-character Unicode strings can also be created with the chr built-in function, which takes integers and returns a Unicode string of length 1 that contains the corresponding code point. The reverse operation is the built-in ord function that takes a one-character Unicode string and returns the code point value:. The opposite method of bytes. The errors parameter is the same as the parameter of the decode method but supports a few more possible handlers.

The low-level routines for registering and accessing the available encodings are found in the codecs module. Implementing new encodings also requires understanding the codecs module.
