hi to everyone.

i am a new member and i am using arch keyboard in order to write thai in my cell phone.
this application is using thai and english letters,is a solution for a third language like greek as it is my nation language?
i do not want to change keyboards all the time so iw there any language pack for greek?
note please that we are a community that we go to thailand very often and a lot of people want a keyboard with thai,greek and english language.

I use LG ME P350
