[PATCH] gitweb: use decode_utf8 directly

["Ismail Dönmez" <ismail@pardus.org.tr>]

[-- Attachment #1.1: Type: text/plain, Size: 1074 bytes --]

Hi,

gitweb currently uses Encode::decode function with a wrapper like this :

# very thin wrapper for decode("utf8", $str, Encode::FB_DEFAULT);
sub to_utf8 {
       my $str = shift;
       return decode("utf8", $str, Encode::FB_DEFAULT);
}

But for me this gives the following error when I try to view RSS feed for 
Linux kernel GIT repo (local checkout) :

Cannot decode string with wide characters 
at /usr/lib/perl5/vendor_perl/5.8.8/i686-linux/Encode.pm line 162.

I Google'd a bit but the relevant information seems to be missing about this 
error. Anyhow there is no need for a wrapper at all as Encode class has a 
decode_utf8 function which fixes the problem I am experiencing too and chops 
off the unneeded wrapper.

Patch against git 1.5.1.2 is attached. Comments welcome.

P.S: I am using Encode 2.20 from CPAN which is the latest stable version 
available.

Regards,
ismail
