I presume you refer to one of a set of documents accessible from
http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&item_id=PUA_home&highlight
It is interesting that SIL has seen the need to include precomposed
combinations with U+0321 palatalized hook and U+0322 retroflex hook.
Perhaps this is because these diacritics cannot be automatically
combined with their base characters. They can of course be included in
an OpenType etc font as ligatures, but only if the rendering engine
supports complex rendering with Latin script - for which the Office 2003
version of Uniscribe is required. But I note that several characters
which are effectively combinations with U+0334 are listed as "approved
for addition to Unicode".
It would be good if Microsoft could put an end to the need for such
kludges (at least on Windows) by releasing this recent version of
Uniscribe as a Windows update.
"U+F25A LATIN SMALL LETTER HENG" is probably not intended as an h-ng
combination but as h with a hook, probably a glyph variant of F222.
There is an error in the alternative encodings for Hebrew right and left
meteg which I will report. The alternative encoding given for "reversed
nun" is objectionable on theoretical as well as practical grounds and so
the PUA character should not be deprecated. The use of U+0323 for lower
dot is also undesirable, except as a short term kludge. Proposals are in
the pipeline for proper characters for reversed nun and lower dot.
