[Devel] Uninitialized variable.

[George Williams]

I just downloaded and built ft2demos from cvs and got a warning:
/usr/local/src/ft2cvs/ft2demos/src/ftdump.c: In function
`put_unicode_be16':
/usr/local/src/ft2cvs/ft2demos/src/ftdump.c:296: warning: `ch' might be
used uninitialized in this function

Looking at the code there is a problem if string_len==0. I don't know if
that is possible or not.
