I was asked to "certify" the Portuguese-to-Quenya transcriptor and
translator below, but I have no knowledge of Quenya. Can someone do that?

Online transcriptor:

Translator (in development):

My interlocutor wants to confirm that he can use those texts as valid
Quenya texts (or non-Quenya texts using Quenya alphabet). It's kind of
peer-review or third-part opinion.

I don't know if the software author is in this list, but I think it's not
impolite to look for opinions others than the author's himself. I guess
that it's actually good for his work.

Até mais!
