RE: [EXTERNAL] Some braille references

Hi Deyan,

I'm confused by what you wrote.  My understanding of Unicode is that it
distinguishes characters from glyphs and that a great deal of effort has
gone into creating the Unicode set of over 100,000 unique characters.
Characters in Unicode are distinguished by their numerical character codes,
not by their visual appearance.  Unicode decided back in 1993 that a colon
punctuation mark and the mathematical symbol for ratio are two different
characters. If my understanding up to this point is incorrect, please
correct me.

It is also my understanding that characters are displayed visually by glyphs
with the Unicode tables providing a typical or reference glyph for each
character.  However the visual appearance of a given character is not going
to be identical in all fonts. 

The use of Unicode character codes aids in the automatic translation of math
to braille.  Of course a given braille system cannot define easy-to-remember
braille symbols for all of the Unicode characters so it needs some method
for dealing with this issue.  One posssibility  is direct representation of
hexidecimal character codes.
