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

I am using one based on this script.

 def strip_emoji(text)
    text = text.force_encoding('utf-8').encode
    clean = ""

    # symbols & pics
    regex = /[\u{1f300}-\u{1f5ff}]/
    clean = text.gsub regex, ""

    # enclosed chars 
    regex = /[\u{2500}-\u{2BEF}]/ # I changed this to exclude chinese char
    clean = clean.gsub regex, ""

    # emoticons
    regex = /[\u{1f600}-\u{1f64f}]/
    clean = clean.gsub regex, ""

    #dingbats
    regex = /[\u{2702}-\u{27b0}]/
    clean = clean.gsub regex, ""
  end

Results:
