Convert unicode characters that resemble ASCII to their equivalent.
Convert unicode to closest ASCII equivalent.
There are many unicode glyphs whose appearance is very similar to ASCII characters. This script converts these codepoints to their ASCII equivalent. For example, the string
і lоѵе üńісοdе contains only 2 ASCII characters, despite the fact that all but
üń look fine at first glance. To convert to ASCII:
> echo і lоѵе üńісοdе | uni2ascii i love unicode
The default action is to leave untouched any non-ascii that
uni2ascii.py doesn't know about. This can be overridden with command line arguments. Call
uni2ascii -h for help.
You can also call from python:
from uni2ascii import uni2ascii ascii_string = uni2ascii('і lоѵе üńісοdе')
It's quite easy to add new transliterations. See the function
__init__.py. Feel free to contact me or do a pull request if you find useful ones that aren't there.
uni2ascii was written to handle particular data we had on hand. There are plenty of missing transliterations. I'm happy to add new ones!
Input encoding must be utf-8.
Feel free to modify - it's not likely it'll work exactly correctly for you out of the box.
The code should work in python2 or python3.
This was not designed to thwart homograph attacks, but rather to help with text normalization of English, where unicode sometimes sneaks in.
pip install uni2ascii
The Python module
Very similar in spirit, but doesn't handle punctuation and makes some choices I disagree with.
If you call
iconv -t //TRANSLIT, it'll do some of what
uni2ascii does, but a bunch of stuff is missing that is important to our application.
Image processing approaches
There have been a few projects that actually look at the generated pixels to determine if two glyphs are too similar. I love the idea, but wanted more fine grain control.
