How to integrate multiple scripts in a single control

Dear All,

I would like to design a multi-script (Ethiopic and Latin) online handwriting
recognition text editor on Palm OS PDA.

I have developed a recognition algorithm for Ethiopic and want to use the built
in for Latin.

I have implemented the algorithm in J2ME environment. However it doesn't support
custom fonts.Then I have moved to use superwaba, but in this case I can handled
the fonts but the problem is to find a control that recognizes pen movement.

So is there any one who can help me in how to solve the above problem.

second, Can I have any means to call for the built in recognition
engine(graffiti)from my application?

Thanks,
any comment is appreciated.
