Otherwise, as long as you aren't doing the replace every frame, it should be no problem replacing many times on the same string. I would maybe make a HashMap of the characters, then you would be able to loop through each of them, rather than stringing (HA!) them all together.

Also, IMHO from a user's perspective, that would be pretty miserable to have to look up and use a made up code to type letters.

good luck!

I haven't actually changed the font in my program, which made me believe (before) this may not be the case. I'll try changing the font to Arial, or another font which I know can use accented letters, and will let you know :)

Also thanks for your advice :) I know it's kinda awkward in it's current form, but I tried to use logic when choosing the symbols before the letter. For example the '/' at the top of '<' indicates the adjacent character will have that accent (é) and ^ before the 'e' gives ê. It was also implemented so that people didn't equally have to look up how to place accented characters using keyboards which aren't designed for them. But I totally understand your view. I might decide later to design a separate text editor to make it easier :)

Also thanks to everyone else who spent time helping! :)

THREAD SOLVED :)

Anyone who's in trouble with setting correct file encoding or figuring out which font supports which characters, here're two posts where I tried to describe in detail how Processing works with fonts/encodings:
