When you want to use Wiktionary as an online
dictionary, you may be able
to convert it to the .dict format. This does not make it acceptable
.dict data. When you query a .dict dictionary you expect the resulting
data to be in a particular language.
I don't think there is a specification that says what is and what isn't
acceptable DICT data, or what one can expect to get back from a query.
(Oh, and, BTW, I think UW is a great project :)
