Regular expression to match non-ASCII characters?

This should do it:

[^\x00-\x7F]+

It matches any character which is not contained in the ASCII character set (0-127, i.e. 0x0 to 0x7F).

You can do the same thing with Unicode:

[^\u0000-\u007F]+

For unicode you can look at this 2 resources:

• Code charts list of Unicode ranges
• This tool to create a regex filtered by Unicode block.
