Stripping every and all emoji from a sentence string

Working environment Python version:

Python 3.6.1

I've tried a number of methods outlined here on StackOverflow and other places around the internet - yet I still can't seem to get this working.

I could have any string...and the emojis may or may not be surrounded by whitespace, may be within " or after a hashtag etc etc...anyways, these circumstances are giving me some troubles.

This is what I have:

import sys
sys.maxunicode

emoji_pattern = re.compile("["
                           u"\U0001F600-\U0001F64F"  
                           u"\U0001F300-\U0001F5FF"
                           u"\U0001F680-\U0001F6FF"
                           u"\U0001F1E0-\U0001F1FF"
                           "]+", flags=re.UNICODE)

text = "" #This could be any text with or without emojis
text = emoji_pattern.sub(r'', text)

The above however when displayed or printed still have the emojis within the text.

text is a unicode string i.e., type(text) returns <type 'unicode'>

So what am I missing? I seem to have emojis remaining. I would also prefer a method that reflects that these Unicode designations could be expanded upon in the future so I would rather just have a method that keeps all regular characters.

Encoding the text as 'unicode_escape' gives the following:

b'[1/2] Can you see yourself as Prompto or Aranea?\\nGet higher quality images from our FB page \\n\\u2b07\\ufe0f\\u2026'

The raw unformatted text is:

[1/2] Can you see yourself as Prompto or Aranea?

Not sure what you think sys.maxunicode does, but your code works with Python 3.6. Are you sure you have all the emoji ranges covered?

import re

emoji_pattern = re.compile("["
                           u"\U0001F600-\U0001F64F"  
                           u"\U0001F300-\U0001F5FF"
                           u"\U0001F680-\U0001F6FF"
                           u"\U0001F1E0-\U0001F1FF"
                           "]+", flags=re.UNICODE)

text = 'Actual text with emoji: ->\U0001F620\U0001F310\U0001F690\U0001F1F0<-'
print(text)
text = emoji_pattern.sub(r'', text)
print(text)

Output:

Actual text with emoji: ->😠🌐🚐🇰<-
Actual text with emoji: -><-

Note that flags=re.UNICODE is the default in Python 3.6, so it is not needed. Unicode strings are also the default, so u"xxxx" can just be "xxxx".
