Answer 2

Use this regex to keep emojis and ascii english characters, and remove everything else: /[\\r\\n]|[^\?-\?a-zA-Z0-9\\!\\?\\;\\:\\$\\#\\@\\*\\%\\,\\'\\"\\<\\>\\+\\(\\)\\.\\-\\_]/g . For example:

 $("#test").click(function() { var msg = $('.foo').text(); msg = msg.replace(/[\\r\\n]|[^\?-\?a-zA-Z0-9\\!\\?\\;\\:\\$\\#\\@\\*\\%\\,\\'\\"\\<\\>\\+\\(\\)\\.\\-\\_]/g, ''); $('.foo').text(msg); });
