What if we just remake this mod anew?

[Nikas Kunitz]

I really appreciate the effort you put in small details! I bet you enjoy doing it, though my concern lys with more in the gameplay balances. Nonetheless I think it will be a sufficient solution for the naming, although I don't speak any of those languages.
What I know, is Hungarian use j as j and i as i and those are not interchangeable. But Hungarian names were already fine.

Yeah, Hungarian uses pretty unique version of Latin script, regarding its digraphs that are easily writeable in Civ4 encoding.
Yes, Hungarian uses j as "short i" sound just as German and Slavic languages, including Russian in transliteration used in this mod. And the rest of digraphs are easily understandable and convertable, comparing Hungarian and this Russian transliteration: cs = ch, zs = zh, s = sh (sz = s), h/ch (in Latin/German borrowings) = kh, (consonant)ya/yu = (consonat)ja/ju (palatisation)
