Missing Greek Numerals and other minor glyphs

[Doc73]

Dear Developer,
I would notice that some glyphs are missing, in particular:

• some greek numbers: 6 (ϛ´) and 90 (ϙ´), even if the corresponding archaic letters exist
• ⟦ (U+27E6)
• ⟧ (U+27E7)
• ※ (U+203B)

These glyphs are very useful in greek philology.

Many thanks in advance.

I don’t understand your first point. Archaic lowercase qoppa and stigma, like digamma and sampi exist in EBG12-Regular. How do you enter them when they don’t come up for you? They’re missing in the Italics, though.

Ah, yes!
I us XeLaTeX with polyglossia package. Here is a sample:

OK. \greeknumeral requires the letters be present in uppercase, at least the error message looks like it:

Missing character: There is no Ϛ (U+03DA) in font EB Garamond 12 Regular/OT:scr
ipt=grek;language=dflt;mapping=tex-text;!
Missing character: There is no ϟ (U+03DF) in font EB Garamond 12 Regular/OT:scr

No! \greeknumeral requires lowercase letters. For uppercase letters you must use \Greeknumeral.
For Ϛ there is a bug: reutenauer/polyglossia#587

Oh, thanks for the information. For me it stays the same — the uppercase stigma and qoppa (and some other archaic characters) are missing.
