Actually, I get a warning with both Lilypond 2.14.2 and the current git
version. I'm using 64-bit Fedora 16. The file is attached (I'm not
sure it would survive if posted inline). The message could be improved,
but it does mention UTF-8.

If there is no such warning for some users, I would consider it a bug
in Lilypond. But we haven't heard any details from the original
reporter yet.
