Question

How do I do a regexp search against a Mandarin string?

Answer 1

In what language? In PHP, use UTF-8 and the /u modifier.

Answer 2

No different that against any other string; of course it requires a language and a regexp library that correctly uses unicode for its strings and doesn't assume that a string is just a byte array interpreted as ASCII.
