Anyone know how it's (will be) realized?
Will it have some special chars removed and substituted with native language chars? Or will it use additional method for typing?

Eg. n97 has different set of special chars which means some other important ones are removed from the keyb.

Damn there's a very smilar topic. Sorry for spamming:
