Font-config can do this, though its documentation, API, and command-line
interface are all rather inscrutable. I wrote a program that can take
any character as input and give you the filename of a font with it.
Just put the two files anywhere, then:
make
./CharSearch ①
I.e. put the character you're looking for as the first and only
argument. Only tested with en_US.UTF-8 as LANG environment variable.
