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

Instead of removing Emoji characters, you can only include alphabets and numbers. A simple tr should do the trick, .tr('^A-Za-z0-9', ''). Of course this will remove all punctuation, but you can always modify the regex to suit your specific condition.
