Thread:User talk:CodeCat/Ogham transliteration/reply (2)

In Module:usex, there's a place where the transliteration is treated differently if the language is Japanese (roman text) or not (all others are italic). Could not a similar exception be added for script=Ogam?

Also, in what module are the transliteration rules? I can't find them, and the code looks like a twisty little maze of dependencies.
