(I am not sure whether it is a Mozilla problem, or a problem in the CSS2
specification.)

When an ordered list's items are numbered using the greek numbering notation
system (greek alphabet letters), as per CSS2 (list-style: lower-greek), the
letters are used (generated) sequentially, which is incorrect.

As with the latin numbering notation, the Greeks developed a numbering notation
system, by assigning letters of their alphabet to represent numbers. However,
the letters of the greek alphabet, as was the case with the latin alphabet, were
not sequentially assigned to numbers. The system, seemingly less arbitrary than
the latin one, is as follows: 

alpha 1
beta  2
gamma 3
delta 4
epsilon 5
* stigma (like final sigma, or latin s -- Unicode: Ϛ) or sigma-tau (not
the appropriate, but still widely used) 6 *
zeta 7
eta 8
theta 9

iota 10
iota-alpha 11
iota-beta 12
...
kappa 20
lambda 30
mu 40
nu 50
ksi (its latin equivalent is x) 60
omicron 70
pi 80
* qoppa (latin equivalent glyph: q -- but not always -- Unicode: Ϟ) 90 *

rho 100
sigma 200
tau 300
upsilon 400
phi 500
chi 600
psi 700
omega 800
* sampi (means: like pi, in Greek -- Unicode: Ϡ) 900 *

All of the numerals, in the units, tens & hundreds range, are followed by the
numeral (or prime) sign (Unicode: ʹ). In the case of the thousands,
however, the numerals are preceded by a similar symbol at their left and at the
baseline (Unicode: ͵). So,

͵α 1,000
͵β 2,000
...

I believe the best way to show you what the correct signs are, is an HTML
document I have authored, which contains an example, the relevant notes, and a
table with the signs and their corresponding numeral values. This document is at
your disposal, upon request -- just let me know how to send it, and were.


Reproducible: Always
Steps to Reproduce:
1. Craft a utf-8 HTML document containing an ordered list of type: list-style:
lower-greek, with more than 1,001 items
2. Open the document in any release version of Mozilla (up to 1.6)
3. Behold!

The prime and the other (lower-left) symbols above, are not used in modern
Greek, in the case of lists

Apologies for any confusion...

:-)

According to http://www.w3.org/TR/CSS2/generate.html#propdef-list-style-type,
lower-greek is an alphabetic system, not a numbering system, so this bug should
be invalid in that context. In CSS2.1 it seems that some of the numbering
systems have been removed http://www.w3.org/TR/CSS21/generate.html#lists, but
nothing changes about greek.
in the draft of CSS 3 again lower-greek is just an alphabetic system.
http://www.w3.org/TR/2002/WD-css3-lists-20021107/#alphabetic

so resolving as invalid.

Ian, Should the proposed system be added to css3-lists?

Comment 4

[Hixie (not reading bugmail)]

If someone proposes it to www-style *with a complete algorithm* and preferably
some supporting documentation, I'll add it.

Thank you all,

I'll contact W3C and make them aware of the problem.
(There should also exist a
list-style-type: upper-greek)
