\markup { "da capo al " \musicglyph #"scripts.coda" }
defaults to vertically aligning the centre of the coda symbol with the bottom of the text. I can change this by using \raise and fiddling with the value for raise until it looks correct:
\markup { "da capo al " \raise #0.8 \musicglyph #"scripts.coda" }
but is there a way of telling Lilypond to align the bottom of the symbol with the bottom of the text without this tweaking. I had a look through the section of the NR dealing with text alignment without seeing anything.
