Thanks for your reply.
This is the abnormal section of the --verbose output:

Preprocessing graphical objects...
Grob count 46

Without using the character, the output is exactly the same, except the 
warning is gone.

$ pacman -Qo /usr/share/fonts/100dpi/ncenR24.pcf.gz 
/usr/share/fonts/100dpi/ncenR24.pcf.gz is owned by xorg-fonts-100dpi 
1.0.1-4

It seems that freetype/pango has somehow decided to select this font, 
which perhaps doesn't provide enough detail for lilypond. I just tried 
to force a font:

\addlyrics {
\markup{
 \override #'(font-name . "roman-12")
 ɔ
}
}

then it works! Seemingly no matter whether I put 'roman' or 'sans'. 
Being quite happy with the Lilypond defaults, I would prefer not to 
mess with the fonts, but it seems like the pragmatic solution here :(

BTW: fontconfig=2.11.1, pango=1.36.3 and gs=9.14, but this is starting 
to look more like a lilypond/configuration issue

Cheers,
Oliver
