I have never seen arrows with accidentals. The vastly predominant
notation for Arabic music uses a sharp with only one vertical bar for
a quartertone shift upwards and a flat with an added almost-horizontal
line for a quartertone shift down, and those are the ones that I
have implemented. See
http://www.farid-el-atrache.com/musicscores/songs/teoolla.html
for an example score using this notation.
There are a few Arabic scores that use inverted flats, and Turkish
typesetters have introduced flats with numerical superscripts for
indicating the different versions of quartertone shifts. Note that
there is no real difference between the Arabic and the Turkish musical
scales, some of the Turkish score writers just aim for a more precise
transcription. However, this precision is not really needed; the key
signature plus the fundamental tone of the scale (easy to find out)
are sufficient to fully define a scale.
I see no problem in providing alternative graphical symbols as an
option, e.g. the inverted flats, assuming that this could be
handled via score attributes. However, I wouldn't want to support
anything more complicated than one kind of quartertone shift.

Thanks, I'll have a look at that one...
