How to escape special characters correctly for a URL

silent11 has asked for the wisdom of the Perl Monks concerning the following question:

What I have: Fútbol con Mayte introducción al fútbol

What I need: F%C3%BAtbol+con+Mayte+introducci%C3%B3n+al+f%C3%BAtbol

What I get with URI::Escape : F%FAtbol%20con%20Mayte%20introducci%F3n%20al%20f%FAtbol

What module can I use to convert what I have, a string with those funky characters, into what I need, an escaped sequence? URI::Escape isn't doing the job for me, I'm sure it is doing it's job correctly, I'm just misusing the module. Any Ideas?

    You're not misusing the module; it seems you don't want the module. If you pass your "what I need" to uri_unescape, you get a mess, so it's clearly not compatible. (At the very least, the spaces-for-pluses translation isn't normal.)

    I think you're going to have to roll your own. How did you determine what you need?

    URI::Escape is using RFC2396 and updated by RFC2732 for encoding and decoding characters that are not alphanumeric (a-zA-Z_0-9 or simply \w).
    Try to figure out what kind of encoding you have to use. Maybe there is an existing module. If not a definition will make it easier for you to write one.
