Convert unicode codepoint to UTF8 hex in python
python, unicode
Solution
Use the built-in function `chr()` to convert the number to character, then encode that:
>>> chr(int('fd9b', 16)).encode('utf-8')
'\xef\xb6\x9b'
This is the string itself. If you want the string as ASCII hex, you'd need to walk through and convert each character `c` to hex, using `hex(ord(c))` or similar.
Note: If you are still stuck with Python 2, you can use `unichr()` instead.
Problem
I want to convert a number of unicode codepoints read from a file to their UTF8 encoding. e.g I want to convert the string `'FD9B'` to the string `'EFB69B'`. I can do this manually using string literals like this: ``` u'\uFD9B'.encode('utf-8') ``` but I cannot work out how to do it programatically.
