[Cython] How to improve the performance when doing string/unicode replace and search?

[Yunfan Jiang]

hi, i used to ask some string process question here, and found  a bug, it
seems you guys fix the bug but not use it

and this time , my problem is about the performance,
i need to wrote  a filter which search sorts of keywords in the target
string , and stop if matched,
this act require unicode input/output  , so i wrote a trie like module to
done it, it works ,but i found its too slower than using regex module
so could you guys give some tips on string process performance?
