Yet another question.

Can you try this:

\markup \override #'(font-features . ("tnum" "cv47" "ss01")) {
  \fontsize #-5 \number "6"
  \fontsize #-5 \align-on-other #0 #0 \number "1" #0 \number "♯"
  \fontsize #-5 \align-on-other #0 #0 \number "1" #0 \number "♭"
  \fontsize #-5 \align-on-other #0 #0 \number "1" #0 \number "♮"
}


It's just the 4 markups that the bass figures end up printing.

You say that for you, \markup \override #'(font-encoding . fetaText) "♯" 
works. This is essentially the same as \markup \number "♯".

I expect the above to fail and print the squares. You also said that it 
worked if one added <6!>, which translates to

\markup \fontsize #-5 \put-adjacent #0 #-1 \number "6" \pad-x #0.1 
\number "♮"

What I would like to understand is the conditions that trigger the 
problem. Can you try to remove things in those markups (also the font 
features) and see what happens, and hopefully identify what exactly is 
causing the issue?
