Need Help with Rldev script repack

[Slash]

Hello.
I've began a tranlation project (to spanish) of こいびとどうしですることぜんぶ (Koibito Doushi de suru coto zenbu).
I could extract the 282 SEENxxxx.txt files and i can repack them (with RLdev, Thanks Haeleth).
The problem is this:








When I write the letter "i" it does not appear in the game, it appears as a empty space (It should be "Mi" but appears as "M"), and I dont know how to make it visible. Please help.
