How Can I Match Non-ASCII Characters Using Regular Expressions in JavaScript/jQuery?

Matching Non-ASCII Characters with Regular Expressions

In Javascript/jQuery, matching non-ASCII characters can be a challenge due to the language's limited character support. However, regular expressions offer an effective solution for capturing these characters.

Regex Matching Non-ASCII Characters

The following regular expression can be used to match non-ASCII characters in JavaScript/jQuery:

[^\x00-\x7F]+

This expression matches any character that is not present in the ASCII character set (0-127).

Unicode Matching

Alternatively, you can use Unicode ranges to match non-ASCII characters. For example, the following regex will match characters in the Basic Multilingual Plane:

[^\u0000-\u007F]+
