Qt's ICU codec indeed doesn't support euc-tw, because it's not even registered 
at IANA:
http://www.iana.org/assignments/character-sets/character-sets.xhtml
(and that's what qicucodec.cpp uses as the base list)

I would just remove it from the prober.

You are right, however, that a runtime check is needed anyway, because one can 
compile Qt without ICU support, and then the list of supported codecs might be 
different.
