Assume GIT command output is utf-8.

LXR uses GIT to fetch the author names from the commits.
The issue is that utf-8 bit is not set on the strings from the output of GIT
commands.
The length calculation is then done on internal bytes rather than utf-8
characters.

WineHQ.org uses LXR version 2.0.2.
LXR version 2.1.0 includes a fix for utf-8 support for GIT commands.
The attached patch is based on that fix.
