KMail needs this too to detect the encoding of attachments when adding them 
from a local file. For KMail/KDE 3 I backported KEncodingDetector but it's an 
ugly beast in more than one way (*) and apparently not the best at doing its 
job anyway.
I am very much in favor of putting Mozilla's detector into a nice class and 
adding that to kdelibs. Are the licenses compatible?

(*) The API is somewhat inconvenient and it also takes a const QByteArray, 
does a const_cast and goes on to modify it. That caused a nice bug in KMail 
which trashed attachments. UGH.
