Or perhaps we can use Unicode Control Pictures U+2400 – U+243F
(9216–9279) ("Unicode quoting"):
http://www.alanwood.net/unicode/control_pictures.html
http://www.unicode.org/charts/PDF/U2400.pdf
# quote unsafe characters and escape filename to HTML
sub esc_path {
my $str = shift;
$str = esc_html($str);
$str =~ s!([[:cntrl:]])!sprintf('<span class="cntrl">&#%04d;</span>', 9216+ord($1))!eg;
return $str;
}
with perhaps the following CSS
span.cntrl {
border: dashed #aaaaaa;
border-width: 1px;
padding: 0px 2px 0px 2px;
margin: 0px 2px 0px 2px;
}
What do you think of it?
