Most of the Vietnamese I know either use VIQR directly, or ignore the
diacritics altogether (putting up with the attendant risk of
miscommunication). One reason for the success of VIQR is that it's easy
for humans to read it and figure out what's going on.
There are still many fonts that don't support the Vietnamese precomposed
characters (see below). VIQR is a fallback that always works.

All precomposed letters necessary for Vietnamese are already encoded,
and have been since Unicode 1.1.
