Hi Colly and Cazador, thank you for your comment.
Actually, colors/names/terms are currently working, that includes 'new window' and 'end dialog' characters. I just didn't create a 'friendly' input method on the UI, but It's planned for next update.
About diacritic characters, hmmm, I've just included compatibility with the characters that are used in the ff8 characters table.
That said, if an user type any character that don't exist in the ff8 char table, cactuar will return the equivalent of "?" on ff8 char table. I don't think I'll be implementing ways of modifications on this issue. The best solution for this user will be, I think, while himself remake the chars he'll use in the ff8 char table, in the editor he must remember everytime he needs that char, he'll need to type the old char value for that one.
I had to do this myself, in my language we use lots of "ã" and in ff8 char table don't have it. I had to modify texture of the "à " as I don't think I'll use in the entire game, for the "ã" that I'll often need. And when editing the dialogs I have to type "à " whenever I need the "ã". Hope you understood what I mean.
I'm focusing in implement comp/decomp of field files directly in the editor. Also I'm thinking in making a preview window, just like Loveless for ff7. But currently I can't seem to find a vb.net control that behaves like I need (multi-colored with background).
