Summary:                    git fast-export producing corrupt output with UTF8
locale on Solaris 11
Description: 
On Solaris 11, using git 2.3.1 or 2.4.0 from OpenCSW, when commiter or
author contain multibyte characters, git fast-export writes extra garbage
after the author/committer line:

$ locale
LANG=en_US.UTF8
LC_CTYPE="en_US.UTF8"
[...]
LC_ALL=

$ git fast-export --all 
blob
mark :1
data 6
Hello

reset refs/heads/master
commit refs/heads/master
mark :2
author Füü Bär <foo at example.com> 1487506001 +0100
co
committer Füu Bär <foo at example.com> 1487506001 +0100


data 6
Hello
M 100644 :1 foo.txt

reset refs/heads/master
from :2



With LC_CTYPE=C the problem disappears (this correct output can be used
with git fast-import to create a test case repository):

$ LC_CTYPE=C git fast-export --all 
blob
mark :1
data 6
Hello

reset refs/heads/master
commit refs/heads/master
mark :2
author Füü Bär <foo at example.com> 1487506001 +0100
committer Füu Bär <foo at example.com> 1487506001 +0100
data 6
Hello
M 100644 :1 foo.txt

reset refs/heads/master
from :2
