That may not be the whole story.  When I trigger the same diagnostic
from mainline GCC in a terminal that doesn't support Unicode, with
LANG set to en_US.UTF-8, I get this:

test.c:5: warning: pointer targets in passing argument 1 of ###foo###
differ in signedness

where each # is a different garbage character.  In other words,
there's garbage around the function name, but the diagnostic is still
readable.  I want to know why Andi is seeing nothing but garbage after
the "of".

There may not be much we can do about this in any case - there is no
programmatic way to probe whether the terminal supports Unicode that I
know of; we are stuck trusting the locale.
