How do I remove emoji from string

Question

My problem is to remove emoji from a string, but not CJK (Chinese, Japanese, Korean) characters from a string using regex. I tried to use this regex:

REGEX =         


        

Answer 1

One more alternative

"Scheiße! I hate emoji                                                                     

                                                        
            

Answer 2

This very short Regex covers all Emoji in getemoji.com so far:

[\u{1F300}-\u{1F5FF}|\u{1F1E6}-\u{1F1FF}|\u{2700}-\u{27BF}|\u{1F900}-\u{1F9FF}|\u{1F600}-\u{1F64F}|\u{1F680}-\u{1F6FF}|\u{2600}-\u{26FF}]

Answer 3

CARE the answer from Aray have some side effects.

"-".gsub(/[^\p{L}\s]+/, '').squeeze(' ').strip
=> ""

even when this is suppose to be a simple minus (-)

Answer 4

REGEX = /[^\u{1F600}-\u{1F6FF}\s]/

or

REGEX = /[\u{1F600}-\u{1F6FF}\s]/
REGEX = /[\u{1F600}-\u{1F6FF}]/
REGEX = /[^\u{1F600}-\u{1F6FF}]/

because your original regex seems to indicate you try to find everything that is not an amoji and not a whitespace and I don't know why would you want to do it.

Also:

• the emoji are 1F300-1F6FF rather than 1F600-1F6FF; you may want to change that

• if you want to remove all astral characters (for example you deal with a software that doesn't support all of Unicode), you should use 10000-10FFFF.

EDIT: You almost certainly want REGEX = /[\u{1F600}-\u{1F6FF}]/ or similar. Your original regex matched everything that is not a whitespace, and not in range 0-\u1F6F. Since spaces are whitespace, and English letters are in range 0-\u1F6F, and Chinese characters are in neither, the regex matched Chinese characters and removed them.
