How to use Javascript-based encoding converter to use with SIL tools (e.g. TecKit)

Hi,

I thought I came across some documentation and repository for using javascript converters with TecKit or another SIL tool.

I have been updating javascript code for converting APS_C_DV_* (Devangari legacy) font into Unicode. I would like to adapt as need and plugin to any SIL tool that would allow me to run it on MS Word documents. It currently only works as copy and paste via HTML text boxes.

Any direction is appreciated!

Peace,
Kaanchan
