Adding a two hex-values character with Hex Editing (P3P)

[Niopack]

Hi guys, after a lot of trial and error, I found a way to edit the encrypted eboot.bin file (Using PPSSPP: Settings>Tools>Developer Tools>Dump decrypted EBOOT.BIN on game boot).

Now I can edit the menus, All-Out Attacks, etc. with hex editing, but I have a question, it's possible to add special characters using just one hex value?

I get a character's hex value using Persona Editor's Visualizer, all the characters I added into the font are coded with two hex values, and that's a problem because it let me without room to edit the text I need to translate! So I was wondering if there was a workaround for this.

It may be a stupid question. I'm really ignorant about this kind of stuff, especially with hex editing, so maybe there is a workaround after all, like using just one hex value for special characters. I just want to know if it's possible. Thanks beforehand, guys.
