I believe most ordinary computer users have not heard of them.  Most
people do not knowingly have the UCD to hand, or even UnicodeData.txt.

Unfortunately, when choosing a character from a character picker, the
most help one is likely to get is the character name.  The name is
actually quite useful when the glyph is not as one expects or the
distinguishing features are not readily visible.

Sometimes, however, the names are distinctly unhelpful. Perhaps
'DEVANAGARI DANDA' should have a correcting alias 'DANDA' (or 'INDIAN
DANDA'?) to reassure people that it is also the Bengali/Tamil etc.

No.  The clear issue raised was of knowing whether a character's glyph
would change with the bidi context.  One solution that immediately

the user's locale. Unfortunately, that will not always work.  In these
days of Unicode, locales are primarily useful for determining the user
