Subject: gitweb: use decode_utf8 directly
X-Git-Tag: v1.5.2-rc2~5^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e3ad95a8be82663d27cb501eaf9bad86a30f9cda;p=git.git

gitweb: use decode_utf8 directly

Using decode() tries to decode data that is already UTF-8 and
borks, but decode_utf8 from Encode.pm has a built-in safety
against that.
