Hi caagr98,
As in https://en.wikipedia.org/wiki/Accent_%28music%29#Anti-accent_marks.
How do I write the first of those? \lheel is similar, but it's not the same.
\version "2.19.62"
unaccent =
-\tweak stencil #ly:text-interface::print
-\tweak text \markup \fontsize #1 \override #'(font-name . "Old Standard")
\char ##x23D1
-\accent
{ c''\unaccent }
If you don't have "Old Standard" installed, try to find another font containing
that glyph.
Hope this helps!
Kieren.
