In a recent interchange with Alexej Kryukov
(See http://www.thessalonica.org.ru/), he clarified for me the relation between the Latin acute and Greek accents.

As I understand it:

The controversy was over the identity of oxia and tonos. The official resolution was that these must be identical.
This does not mean they have to be identical with the Latin acute accent.

For FreeFont, this is helpful, because the Latin acute there (based on the seed font, Nimbus) is very long and shallow. This takes up a lot of horizontal space when put between psili and a capital letter, for instance. It is better to use a more upright oxia for this.

So I have taken the Greek accents for FreeFont directly from TemporaLCGUnicode.

In CVS.

Fixed in CVS

Problem affected almost all the fonts, but not always quite the same way. Fortunately, most of the tonos letters were made of references to tonos, so by making tonos to be a reference to combining accent acute, the problem was mostly fixed. Only some spacing issues remainde.

Let's leave this open until that 'ptolomey' site has been made aware that the problem is fixed in FreeFont.

In FreeSerif U+03AC (alpha-tonos) is composed of U+03B1 and U+0384 (tonos), which seems to make sense. However,

In http://www.unicode.org/charts/PDF/U0370.pdf,
U+03AC is composed of U+03B1 and U+0301
(combining acute accent, which is the same as Greek oxia)

From http://ptolemy.tlg.uci.edu/~opoudjis/unicode/unicode_gkbkgd.html : "So if a user is using a font which has a tonos distinct from the acute, and types polytonic Greek, conflating the oxia and tonos will lead to unacceptable results."
"The real solution is simply to avoid any font for polytonic Greek where the tonos is not an acute"
"The polytonic fonts with a tonos other than the acute are:
Adobe Minion Pro
Caslon
FreeMono
FreeSerif
..."

FreeMono seems to have acute-like tonos, but the combined characters like U+03AC seem to have U+02C8, not Greek tonos, with them.

FreeSerif has a tonos like an upward stroke, not like rising acute. Combined characters have Greek tonos with them.

I suggest that in FreeSerif the tonos (U+0384) will be changed to be like basic acute (U+00B4), or better: Greek oxia (U+1FFD). Maybe in FreeMono the combined characters should use tonos or oxia, not U+02C8.
