So you have a string like this: "任天堂", and you have a template for submitting a query containing that sort of string, which is:
http://www.play-asia.com/paOS-19-71-6-49-en-15-{your_string_here}-43-6 +.html
(I hope I'm parsing that correctly, but I have to say it looks a bit implausible.)

And in order to plug that sort of string into that query template, you have to:

  1. break the string into separate characters;
  2. convert each character into its decimal numeric Unicode code point value
  3. embed each numeric character value between "&#" and ";"
  4. do the "uri encoding" that turns "&", "#" and ";" into "%26", "%23" and "%3B", respectively

So, where's the problem? Have you tried something like this?

my $url = http://www.play-asia.com/paOS-19-71-6-49-en-15-XXX-43-6.html my $string = "..."; # wherever you get your Unicode Asian string from $string =~ s/([^[:ascii:]])/"%26%23".ord($1)."%3B"/eg; $url =~ s/XXX/$string/;
