... as before, I'm using utf8 or euc encoded strings...

Okay, how do you know when you're using one or the other? Does the web site (play-asia.com) support both encodings, and if so, how do you tell it which one you're using?

ord returns the numeric representation of each byte, not each character. The above gives 6 distinct codes, not 3.

6 numerics instead of 3 for that 3-character string definitely means "not utf8" (so presumably euc, based on what you've said); if the web site is looking for utf8-encoded numerics, you should use Encode to convert from euc to utf8, then use ord():

use Encode;
...

my $string = "...";  # wherever you get your euc string from;
$string = decode( "euc-jp", $string );  # now it's a utf8 string;

... # plug it into the url as described earlier

What does "rovf" mean, and am I missing your point(s) completely? (sorry-- I just realized that "rovf" was another monk -- moving right along...)

Your descriptions and replies are a bit hard for me to follow. And what do you mean by "the values are actually just HTML representation"? There are numeric character entity references (both decimal and hex, used in HTML, XML, SGML), there are symbolic entity references (like "á"), and there are uri-encoded versions of these (with the punctuation marks converted to "%" followed by two hex digits).

Are you really still having a problem with this?
