[PATCH] git-p4: import utf16 file properly

[Chris Li <git@chrisli.org>]

The current git-p4 does not handle utf16 files properly.
The "p4 print" command, when output to stdout, converts the
utf16 file into utf8. That effectively imported the utf16 file
as utf8 for git. In other words, git-p4 import a different
file compare to file check out by perforce. This breakes my
windows build in the company project.

The fix is simple, just ask perforce to print the depot
file into a real file. This way perforce will not performe
the utf16 to utf8 conversion. Git can import the exact same
file as perforce checkout.
