Display Emoji in Python's console

I wonder if it's possible to print Emojis in a Python 3 console on Windows. Actually, to avoid the following error:

codec can't encode character '\U0001f44d' in position 10: character maps to
<undefined>


I've used:

import emoji as moji
print(moji.emojize('Python is :thumbsup:', use_aliases=True).encode('unicode-
escape'))


which is, as expected, printing the right
character:U0001f44d
without any
exception
.

Answer

The Windows console has a lot of limitations with regards to Unicode characters, especially those outside the basic multilingual plane(BMP, or U+0000 to U+FFFF). The console defaults to a legacy OEM encoding (cp437 on US Windows) and has limited font support characters outside the localized encoding. Find a Python IDE that has good support for UTF-8.

One quick-and-dirty way to see a wide variety of Unicode characters is to write to a file and leverage the browser:

import os
with open('test.htm','w',encoding='utf-8-sig') as f:
    f.write('\U0001f44d')
os.startfile('test.htm')

This displays thumbs up in the latest Chrome browser on my Windows 10 system.
