Re: Combining characters

[Daniel Glassey <danglassey ntlworld com>]

Hi,
This looks like exactly the kind of situation where silgraphite could be 
useful. (http://graphite.sil.org) - one thing it can do is map unicode 
sequences to the PUA. The pango integration isn't quite there yet but 
hopefully shouldn't be too long.

Hopefully someone on the graphite list can explain what you would need to do.

Regards,
Daniel
