I have just read the posting regarding UNICODE.

May I put UNICODE into perspective for readers who know nothing about it.

ASCII is a 7-bit character encoding standard.

ISO-8251-1 to ISO-8251-15  (I think that the ISO number is correct) are
fifteen 8-bit character encoding standards.  All use ASCII for the lower
half, but have different variants for the upper half of the character set.
The variants are classified as "W European", "E European" etc.  The upper
half of ISO-8251-1 contains characters like �,�,�,�,�,�,� etc (I am writing
this on a German keyboard).

UNICODE is a 16 bit character encoding standard (65,565 possible
characters).  The first 255 characters are the ISO-8251-1 character set.
Not all the remaining characters have been allocated.  Groups of characters
have been reserved for Modern Greek script, others for Ancient Greek, other
for Cyrillic, Hebrew, Arabic and also the various Asian languages.  There
is a set of currency symbols etc.  Large numbers of UNICODE locations are
as yet unallocated.  Special interest groups can petition the UNICODE
committee to allocate spaces for their opwn character set - I know that the
Star Trek community are trying to get the Klingon alphabet recorgnised as a
standard subset of UNICODE.

In response to the original posting - UNICODE represents what typographers
want today and if if accomodates Ancient Greek symbols alongside the
ancient Anglo-Saxon "thorn" symbol, then I see no point in trying to make
them remove a few symbols that represent Imperial units.  Rather we should
use the faxct that these weird symbols exist, while the only nojn-Latin
symbol needed for metric measure is � (mu).

BTW, the Anglo-Saxon "thorn" symbol was pronounced "Th" and looks a little
like a "Y" hence all the shop signs "Ye olde whatever".
