Wow thanks, that kicks ass! Excellent.

Because the ancient greek systems have no missing digits, right?

Seems odd that the newer system would be technically inferior...

This is the only system that is not defined for such an odd range of
numbers. Are you really sure that modern greek numbers are only defined in
the range:

   1..89, 100..189, 200..289, 300..389, 400..489, 500..589, 600..689,
   700..789, 800..889, 1000..1089, 1100..1189, 1200..1289, 1300..1389,
   1400..1489, 1500..1589, 1600..1689, 1700..1789, 1800..1889, [...] 
   889700..889789, 889800..889889.

...?

That seems incredibly inconvenient.

By "your addition" do you mean that normal modern greek doesn't include a
space and is ambiguous? Should the ancient greek forms have spaces?

How about U+00A0 non-breaking space? Or U+2007 figure space?


> ancient-greek
> lower-modern-greek
> upper-modern-greek

Are these your preferred names?

How about ancient-greek, lower-greek, upper-greek, lower-greek-alpha,
upper-greek-alpha?

Or, greek, lower-modern-greek, upper-modern-greek, lower-greek,
upper-greek?

How about 'greek' as a shorter name for the 'lower-modern-greek' variant,
so that the names are: ancient-greek, lower-modern-greek and greek,
upper-modern-greek, lower-greek, upper-greek?

What do other people think?

Is "numeral-sign" a (sometimes absent) suffix, or is it part of the
number? If it is part of the number, what would be the typical suffix? (In
decimal, the suffix is '.' because lists go '1.', '2.', '3.', ...)

Cool, thanks. (FWIW, all i need are the codepoints. The rest means very
little to me. :-) I use the codepoints to include examples in the spec.)

766? :-)

...(where the space is needed to differentiate 200300 from 6000).

So would U+2007 be ok for that space? It seems like a good match for
me. What do long greek books do for their page numbers?


> Note: 6 & 200300 could be ambiguous in modern greek, without the space. 

How? Surely the U+0375 makes it unambiguous.


What would 891918 be?

Is there an example on the net of th 'modern' systems in use? Or anywhere
in fact? I'd love to see this in practice, especially how they cope with
the ambiguities and the 90 and 900s.
