How Can I Match Non-ASCII Characters with Regular Expressions in Javascript/jQuery?

Matching Non-ASCII Characters with Regular Expressions

In various programming scenarios, it becomes necessary to match non-ASCII characters, which are characters that fall outside the traditional ASCII character set. This is particularly relevant when dealing with multilingual text or content from different cultures. In this article, we will explore the easiest way to match non-ASCII characters using regular expressions in Javascript/jQuery.

Solution:

To match non-ASCII characters in a regular expression, use the following pattern:

[^\x00-\x7F]+

This expression matches any character that is not contained in the ASCII character set (0-127, i.e., x00 to x7F). Alternatively, you can use the Unicode version:

[^\u0000-\u007F]+

This expression matches any character that is not contained in the Unicode character range from u0000 to u007F.
