Hi Orm,
maybe the smufl compliant ekmelos
<http://www.ekmelic-music.org/en/extra/ekmelos.htm> font is useful for
you. It also defines some Unicode glyphs like circle and arc arrows. The
following (similar to Pierre's
<https://lists.gnu.org/archive/html/lilypond-user/2024-02/msg00095.html>
proposal) uses the path from ekmelos.svg of the Clockwise gapped circle
arrow (U+27F3) which is maybe more appropriate than the
stringsScrapeCircularClockwise glyph (U+EE88) in smufl.

You can use esmuflily
<http://www.ekmelic-music.org/en/extra/esmuflily.htm> to draw smufl
glyphs in Lilypond as in the following sample. But in case of svg
backend it embeds the codepoint of a smufl glyph, not the path. So you
will not obtain a stand-alone svg file.

Hi,
I'd like to make a sign for circular bowing like in the attached
png. The example was done using an epsfile, but unfortunately that
doesn't export to svg, which I need. So it should be done using
lilypond's builtin markup commands (or scheme code). Can someone point
me to examples to do circular arcs with attached arrows (can also be
scheme code)?
I couldn't find anything similar in the docs/internet.
