gitweb highligh generate illegal char when the content had utf-8 chars

[zzs <zzs213@126.com>]

When my C file had some utf-8 comments, gitweb highlight generate
illegal chars.

So I hacked gitweb.cgi, like this:

---------------------------
diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl
index dab89f2..48def38 100755
--- a/gitweb/gitweb.perl
+++ b/gitweb/gitweb.perl
@@ -6465,7 +6465,7 @@ sub git_blob {
                        $nr++;
                        $line = untabify($line);
                        printf qq!<div class="pre"><a id="l%i" href="%s#l%i" class="linenr">%4i</a> %s</div>\n!,
-                              $nr, esc_attr(href(-replay => 1)), $nr, $nr, $syntax ? $line : esc_html($line, -nbsp=>1);
+                              $nr, esc_attr(href(-replay => 1)), $nr, $nr, $syntax ? to_utf8($line) : esc_html($line, -nbsp=>1);
                }
        }
        close $fd
---------------------------


And it works.

But I wonder is this the rigtht solution.

Anybody help me?
