Question

How do I remove strange and unwanted Unicode characters (such as a black diamond with question mark) from a String?

Please tell me the Unicode chara

Answer 1

To delete non-Latin symbols from the string I use the following code:

String s = "小米体验版 latin string 01234567890";
s = s.replaceAll("[^\\x00-\\x7F]", "");

The output string will be: " latin string 01234567890"
