I've added a command-line converter,

Browse source 
org.thdl.tib.input.TMW_RTF_TO_THDL_WYLIE.  It converts RTF files
consisting of TMW characters to the corresponding THDL Extended Wylie.

It supports --find-some-non-tmw mode, which allows you to ensure that no
unusual characters will spoil the conversion.  The converter has built-in
intelligence that allows it to handle Tahoma '{', '}', and '\\' characters
properly.

The converter works on mixed Roman/TMW also, but --find-some-non-tmw
and --find-all-non-tmw modes are not as useful.

Invoke org.thdl.tib.input.TMW_RTF_TO_THDL_WYLIE, which resides in
Jskad's jar, with no command-line options to see usage information.
