/* Arguments: the character (main), and the modifier (accent, etc). See the
function if you want to know the modifiers.
Description: This function intends to be a small helper, to avoid having
to write switches in functions. It's therefore mainly to accents, and
specially for the most usual ones. It supports the basic greek
characters too, which is actually not very helpful.
Returns: the unicode character corresponding to the composed character.
ToDo:
- It seems to me, that tables should be more effectiv.
So we should use tables in future? (js)
