Dear Ross,
The origin of this coding is surely Adobe’s stated way to establish a default for which character to select for Copy/Paste, Searching, etc.
I think we have to ask the author, Thanh, on the issue. It seems that he considers everything after the first dot shows a feature, but is not a part of a glyph name. As you say, I can't find a period in glyph names aglfn.txt, glyphlist.txt, zapfdingbats.txt by Adobe. Thanks, Akira
