[MEI-L] Half flat (Arabic quarter-tone flat)

Hello Charbel,
It would be possible in MEI now to encode using the flat with a slash
through it to represent a quarter-flat symbol.
The SMuFL font includes such an accidental:
http://www.smufl.org/version/latest/glyph/accidentalBakiyeFlat
from this group of accidentals:
http://www.smufl.org/version/latest/range/arelEzgiUzdilekAeuAccidentals
More specific description of accidentals can be added to notes in MEI using
the accid element attached to note elements:
http://music-encoding.org/guidelines/v3/elements/accid.html
So encoding such a flat currently in MEI would be:
<note dur="4" oct="5" pname="e">
<accid* accid="1qf"* *glyphnum="#xE442"* />
</note>
The attribute "glyphnum" specifies the SMuFL character number which is E442
for the flat symbol with a slash through it.
I have tried this encoding in verovio, and it is not implemented. You
could add a request for implementing in verovio here:
https://github.com/rism-ch/verovio/issues
(requires that you have a free account on github to post the request).
Here is the previous example I encoded using the E442 glyphnum for:
<?xml version="1.0" encoding="UTF-8"?>
