URL-encoding in redirect?

[eluser]Christoffer[/eluser]
Hey,

I am building a search function and I need to create easy to read URLs for bookmarks etc. This is a Swedish application first which means we need to support some special characters (å, ä, ö) that are not supported in URLs.

Therefore I need to encode the variable before it's posted to the user. The PHP function rawurlencode() works when I print the variable with echo() but neither redirect() nor header("Location: x") uses the encoded value.

Why is this and how can I work around it?

Code:

<?php
  // THIS WORKS!: echo rawurlencode((string)$query);
  $keyword = rawurlencode((string)$query);

  // This won't
  redirect('/search/' . $keyword );
?>

Thank you!
