Colud harta be used to wirte Finnish and Estonian? Whie orginally deveplod for Hungarian, it seems that it would make sense to adapt it for Finnish as Estonian as well. While Finnish distinguishes between short and long vowels, as far as I know, only short vowels are word initial, this mean that the same vowel carrier colud be used for both long and word initial vowels, I don't know that much about Estonian.

Of course it is possible, but has Harta gained a following in Hungary? If it can be adapted for use on a cellphone for texting it has a chance.

Possibly it can be used to write Finnish an Estonian, but how to write Finnish letter ä (and å, only in foreign names and loanwords) and Estonian letter õ?
