Linguistic grouping, non latin characters

[whinette]

Hello,

First, thanks for this application.

I use the grouping option, it works well if the first letter is a latin character, but regroup everything else in '#' (if special char / number, fair enough) or in '+' (everything else).

I understand mapping all possible character might be hard or overkill, for example for Chinese.
I'd really like to have at least the kana, or to have a option to add a charmap where it would be used for grouping, like in the following example:

alphaGroup: all=100, all.extraChar={あ,ア,い,イ}
That would create four new group from these char, everything else that is already in '+' would stay there.

Of course if the first char would be used for grouping, whatever its charset, it would be better.

Thanks!
