bug#20537: 25.0.50; `compose-string-internal` does not work properly on OSX. |

I was not able to get this `test-fn` example to work using the latest Emacs
Trunk built early in the morning on May 12, 2015. The echo area should display
the capital letter A with a vertical pipe running through the very center of
the letter; however, the pipe is not even visible -- just the letter A appears
in the echo area.
I am using OSX Snow Leopard 10.6.8: GNU Emacs 25.0.50.1
(x86_64-apple-darwin10.8.0, NS appkit-1038.36 Version 10.6.8 (Build 10K549)) of
2015-05-12 on server.local
