Subject: [PATCH] Gitweb: Fix encoding to always translate rather than 
sometimes fail

When performing the utf translation don't test if $res is defined. It appears that it is defined even when the conversion fails. This causes failures on the writing of the output stream which is expecting UTF.

Instead, immediately return if conversion is successful else force
the translation to the fallback encoding
