Hi,

Can you try like the following ( please note i removed capital letters to get different output ):

Code:
if [[ "avc123" =~ [a-z0-9èàù] ]]; then echo matches; else echo "does not match caps"; fi
matches
if [[ "ABC" =~ [a-z0-9èàù] ]]; then echo matches; else echo "does not match caps"; fi
does not match caps
if [[ "èxuàtiù" =~ [a-z0-9èàù] ]]; then echo matches; else echo "does not match caps"; fi
matches

SYNOPSIS

	 my $empty = GStreamer::Caps::Empty -> new();

	 my $any = GStreamer::Caps::Any -> new();

	 my $structure = {
	   name => "urgs",
	   fields => [
	     [field_one => "Glib::String" => "urgs"],
