Folks,
I have a problem with the EB Garamond family: it contains the glyph "ͤ"
(U+0364, COMBINING LATIN SMALL LETTER E), however, it has neither an
anchor point nor is it part of the font's "mark" table – in
particular, I need support for the combination "oͤ", as used in old
German texts.
To fix this, I would like to use `fonts.handlers.otf.addfeature`. Is
there an example somewhere how to do that? I could only find samples
for other, simpler GSUB and GPOS lookup types but nothing for
"marktobase", which is needed here. In case there is documentation
already available please give me a link.
Werner
