New feature: A TWiki-based application that composes a URL with parameters needs to encode the URL string.

Documented in TWikiVariables:

%URLENCODE{"string"}% Encodes a string for use as a URL parameter. Ex: %URLENCODE{"spaced name"}% returns spaced%20name

In TWikiAlphaRelease and TWiki.org.

Pardon my ignorance, but where would this be used? Sorry for the late question...

One example of using this would be passing a spaced string to another page as a parameter, e.g. [[http://twiki.org/cgi-bin/view/Sandbox/RichardsPage?foo=hi%20there test link with parameter 'foo']] would generate test link with parameter 'foo'. This could be used to drive a CGI program, or if it's a TWiki page you could use %URLPARAM to embed the parameter wherever needed (which is what I've done in this example. Since the parameter could (probably) come from a form or a variable, this is quite flexible.

This would also be useful in passing in a subject line for a mailto: link when using EmailThisPageLink.

Peter probably has a more real-world example!
