[RM2K3] HOW TO MODIFY "ENTER HERO NAME" FORM

Hi! ^^
Sorry, that after that I have actually nothing interested to say but a question, but I searched the whole Internet and I already gave up... Is there some way to edit/add custom letters to "Enter Hero Name" form (RPG Maker 2003)? I mean letters specific to the language, like here, marked in red:



A place in program code, where I could do that, could be enough I think - then I could add letters ascii in hex editor. Last time I downloaded ResHack too, but he can't find it too or don't show it in plain text.

I thought that if you here don't know that, then nobody knows.

Thanks in advance!
