What is the correct IBM GCGID value for U+03B8 GREEK SMALL LETTER THETA? Is it GT610000 or GT610002?
The Unicode 1.1 lists (UNICHP6B.TXT and UNICHP6C.TXT) are inconsistent in this regard. Some entries, even within the same file, show GT610000 while others show GT610002. The tables printed in Unicode 1.0 book are the same. IBM has a Web page containing many PDF charts of code pages, and they have the same problem: some show one GCGID for U+03B8, others show the other one. I suppose this might have had something to do with confusion over U+03D1 GREEK THETA SYMBOL, but that character (a glyph variant of U+03B8) has been in Unicode since 1.0. Was there some dispute at that time over the preferred glyphs for U+03B8 and U+03D1? I remember that they were swapped in Unicode at one point. Was the inconsistency in GCGID a precursor to the decision to swap glyphs? Any ideas? (It's probably best not to ask why I am paying attention to GCGIDs in the first place.) -Doug Ewell Fullerton, California
