strip_emoji.py

import re

# http://stackoverflow.com/a/13752628/6762004
RE_EMOJI = re.compile('[\U00010000-\U0010ffff]', flags=re.UNICODE)

def strip_emoji(text):
    return RE_EMOJI.sub(r'', text)

print(strip_emoji('🙄🤔'))

hello, I credited your work for a workaround in a youtube-dl issue:
ytdl-org/youtube-dl#5042 (comment)
it has helped a lot, thank you.

In case someone like has from __future__ import unicode_literals at the top, then you need to escape "-" like this:

    EMOJI_PATTERN = re.compile(
    "["
    "\U0001F1E0-\U0001F1FF"  # flags (iOS)
    "\U0001F300-\U0001F5FF"  # symbols & pictographs
    "\U0001F600-\U0001F64F"  # emoticons
    "\U0001F680-\U0001F6FF"  # transport & map symbols
    "\U0001F700-\U0001F77F"  # alchemical symbols
    "\U0001F780-\U0001F7FF"  # Geometric Shapes Extended
    "\U0001F800-\U0001F8FF"  # Supplemental Arrows-C
    "\U0001F900-\U0001F9FF"  # Supplemental Symbols and Pictographs
    "\U0001FA00-\U0001FA6F"  # Chess Symbols
    "\U0001FA70-\U0001FAFF"  # Symbols and Pictographs Extended-A
    "\U00002702-\U000027B0"  # Dingbats
    "\U000024C2-\U0001F251" 
    "]+"
    )

or you will got a bad character range like in this SO

Thanks for you help.

def add_space_between_emojies(text):
    '''
    >>> add_space_between_emojies('Python is fun 💚')
    'Python is fun '    
    '''
    from advertools.emoji import EMOJI
    EMOJI_PATTERN = EMOJI
    text = re.sub(EMOJI_PATTERN, r'', text)
    return text

Sorry to say this but I think @mgaitan's regex is not perfect.
The recent emoji character includes various combinations and patterns so it would be more complex expression.
And this would be good implementation example by javascript: https://github.com/mathiasbynens/emoji-regex

@clichedmoog you are totally right, everything here is a simplification

. For a complete/accurate emoji remover for python I recommend the library https://github.com/bsolomon1124/demoji which download the latest emoji specification to build the pattern. It's not super fast but it's exhaustive.
