Related to my question on how to handle multiple glyphs for one Greek
character, there are seeming inconsistencies where Unicode provides more
than one codepoint for a single Greek letter.
Symbols vs. Letters:
When typing a lunate Sigma in a Greek inscription, I can chose either U+03A3
GREEK CAPITAL LETTER SIGMA or U+03F9 GREEK CAPITAL LUNATE SIGMA SYMBOL
(listed in UC 4.0 beta as an "archaic letter"). Visit my chart at
http://parthia.com/fonts/glyphchart.htm to see nine variants of Sigma used
in numismatic inscriptions, only one of which is lunate Sigma. More glyph
forms are found in non-numismatic inscriptions. Since there is no apparent
difference in meaning, but only a difference in the artistic style of the
glyph, does the "symbol" connotation somehow explain why two letters with
the same meaning have been placed in Unicode?
If I am typing a Greek inscription, how do I decide whether to use U+03DE
GREEK LETTER KOPPA or U+03D8 GREEK LETTER ARCHAIC KOPPA? Aren't these the
same letter with a difference only in artistic rendering? Unicode does not
use the "symbol" connotation in this case. Why give two artistic forms of
the same letter?
Could someone please explain why there are duplications?
