As of this writing, I am doing some research on this topic. At least,
I went through almost all the documents that are listed here:
https://unicode.org/versions/ (in reverse chronological order), and
couldn't find any statement of Greek oxia being deprecated in favor of
tonos, contrary to what is claimed here:
https://wiki.digitalclassicist.org/Greek_Unicode_duplicated_vowels
Strictly speaking, tonos is not to be mistaken for oxia: that is for
sure, as tonos was introduced as a result of a reform to denote a
tone, namely a stress on some vowels, and not a pitch, namely a rising
and falling voice on accented vowels. Confusion began in 1986 (from
what I learned) when the Greek government decreed that tonos shall be
the acute. In addition to this, Unicode initially served both Greek
and Coptic on the same block, starting at U+0370. At this time, only
monotonic Greek was served. Later, an additional block called Greek
Extended was added at U+1F00, let alone further additions being
encoded in the Supplementary Multilingual Plane...
>From what I could see, many Greek fonts originally reflected the
distinction between tonos and oxia. But nowadays, they simply mix
them up. This is precisely why I was not able to instruct FontForge
to take into account vowels with oxia in some of the substitution
rules of Old Standard which is a very fine Greek font (see
https://ctan.org/pkg/oldstandard): vowels with oxia were simply
missing from the Greek Extended Block, and what I did not see is a
rule that instructed to absorb vowels with oxia into vowels with tonos
as the glyphs are all strictly the same.
One question remains—and I wish to express my gratitude to all of you,
Robert, Basil and Eli: since assigning vowels with tonos and vowels
with oxia to the same code points is clearly unacceptable even if the
glyphs may be identical, is there a way to input tonos and vowels with
tonos with emacs? I use greek-ibycus4, but if other input methods
can handle these letters, I would consider any change unnecessary.
Many thanks again to all of you!
Robert
