Please update my previous report (in L2/06-378 public review)
on numeric values for some precomposed Hangul syllables with the
following more extensive report.


===================================================================


Sino-Korean number syllables.

There are Sino-Korean syllables (they are all monosyllabic) for
the digits 0-9, and for the numbers 10, 100, 1000, 10000, 100000000,
1000000000000 (the same limit as used for the Han ideographs given
numeric values in UCD). These are used for spellout of numbers in
the same way as Han ideographs are used for spellout of numbers.
There are also native Korean digit/number names, but several of
them are polysyllabic, which disqualifies them for this proposal.

For the Sino-Korean number syllables listed below, the following holds:

1) They are written in Hangul, which is basically exclusively used
   for Korean (transliterations apart), so while phonetic in nature,
   the script in practice here resticts the possible languages to
   one language.

2) They are given one character each (not just a string of characters 
   each, though they each have a canonical decomposition). Ideally,
   and for preservation over canonical equivalence, the canonically
   equivalent strings should also be assinged numeric values. However,
   I do not propose explicitly assigning numeric values to strings
   of characters as that would be a major change in format for
   DerivedNumericValues.txt. (But I do not oppose it either, in which
   case also the native Korean digit/number names (many are polysyllabic)
   should be formally given numeric values in DerivedNumericValues.txt;
   not sure where to put the primary data though.)

3) They are used in the same way as the corresponding Han ideographs
   for spellout (though not used in a positional system, except for
   things like phone numbers and the like which have no composite
   numerical value).

These characters should be given numeric values in DerivedNumericValues.txt
(indirectly from the Unihan database, as several of the numeric valued
Han ideographs are also given kHangul values).

This is admittedly very close to, or rather is, basic spellout of
certain values, but that is the case also for many other characters
given numberic values, in particular Han ideographs given numeric value.

According to the Wikipedia article http://en.wikipedia.org/wiki/Korean_numerals
there are North and South variants for the syllables for (traditional
form) zero and six, as well a special name (gong) corresponding to the
"modern" Han zero (U+3007).
