@msmalik681 basically á é í ó ú can combine with all other characters, except:
- The following combinations do not exist:
áa, íi, óo, úu (accent on first vowel - but ée does exist).
These combinations do not exist: aá eé ií oó uú (accent on the latter vowel)
¿ ¡ can cobine with any other character except for ñ
ñ will always be in combination with a vowel before and after for instance: aña añe añi ...etc so these are the valid combinations of two characters:
añ, eñ, iñ, oñ, uñ, ña, ñe, ñi, ño, ñu
If more "cut" is needed, we can eventually skip considering á é í ó ú > I could then just leave them aside and use a e i o u, that would not be a problem.
The only "real" need is the character ñ, the rest we could live without them (it will not be perfect, but it will not look bad either, in fact very little games have been translated adding accents in vowels and opening exclamation/question marks.
