Could you give us an example? What is important is whether filename
is passed via path_info or via query string.
Because in evaluate_uri() there is
our $path_info = decode_utf8($ENV{"PATH_INFO"});
and in evaluate_query_params() there is
$input_params{$name} = decode_utf8($cgi->param($symbol));

There should be no problem with output encoding. esc_path(), which
should be used for filenames, includes to_utf8, which in turn uses
decode($fallback_encoding, $str, Encode::FB_DEFAULT);

Hmm... all %input_params should have been properly decoded
already, how it was missed?
Also, branchname (hash_base etc.), search query, filename in file_parent,
project name can be UTF-8 too, so it is at best partial fix.
