I have Asian font imported trough Font Maker.
When that said, I don't think any of these problems has anything to do with the font because:
For 1:
When I write "something in normal characters" using english keyboard like "just some text" in the language text file, the asian characters appear.
If I go to google translate and translate the text into asian, and then copy and paste the results into the text file, then it does NOT appear.
For 2:
When I use a english keyboard, the characters appear. To write something sensible I need to know which key on the keyboard to press (as I was using a asian keyboard) in order to get the right character, but it works.
If I however switch to asian keyboard, then suddenly nothing can get typed, meaning something gets typed BUT the input field is deleting everything I type (must be some check routine deleting whats typed).
