TMW for U+0FAD) is not yet committed, but will be soon.

this column.&nbsp; (Note that TMW is a superset of TM, so there is
one glyph in TM that could reasonably appear twice, mapped to both
TibetanMachineWeb7.90 and TMW7.91.)&nbsp; <i>But note that Jskad

the ACIP {<tt>W+W+W+KA</tt>} into Unicode -- and thus cannot
internally use the TMW glyph alone to represent arbitrary Tibetan
text.&nbsp; And the Extended Wylie Transliteration is not a unique
key either; see, e.g., the many glyphs that EWTS
{<tt>r</tt>}.&nbsp; For this reason, a smart tool uses the pair
(EWTS,&nbsp;TMW) as an internal representation.&nbsp; (In Jskad,
this is done in a way that's hard to understand, but it is done --
see, e.g., the code implementing the TMW-&gt;ACIP conversion of
TibetanMachineWeb7.69.)</i>
