[XeTeX] TECkit mapping for Beta Code?

No Teckit mapping but I have a utility written in C 
that converts Beta Code to unicode. 
It also handles all the special symbols prefixed with {,<,",[,# et.c.
Latin text is ignored provided it is enclosed between a & and a $. 


Please email me or post a sample here to see if I can help.
