Yes. I think so, too.
Because I don't know languages other than Japanese.

In libkencoding, User/App uses only one detector at a time like khtml does.
User/App select one detector using locale or config or etc. like selecting QTextCodec.
The developer improve only detector of language he/she understand.


Creation detector using combination of encodig is better.
Especially, UTF-8 and US-ASCII should be supported by all detectors.
But currently only JapaneseDetector supports.

But combination of encoding is not easy.
Maybe the possibility of the misdetection is high. 
( ex. Qt's QTextCodec::codecForContent() is not useful. )

DFA approach like kencoding/detectjapanese.* is maybe one way.
But knowledge base code will need, maybe.
