[PATCH 1/3] precompose_utf8: drop unused variable

The result of iconv is assigned to a variable, but we never
use it (instead, we check errno and whether the function
consumed all bytes). Let's drop the assignment, as it
triggers gcc's -Wunused-but-set-variable.

This is obviously completely optional; I just needed it to get the
"precompose on Linux" hack to build at all with my usual "-Wall -Werror"
settings. I guess clang doesn't have a similar warning, or maybe people
on Macs are not as pedantic as I am.
