[Newbies] HTTP encoding into UTF8

hello,

I am playing around with squeak to connect to webservices and I run into issues very early in the process. Something to do with url encoding. Is there any reason the following code:

'aa aa éé aa aa' encodeForHTTP

would generate this:

'aa%20aa%20%C3%A9%C3%A9%20%A9aa%20%A9aa'

where "space" is correctly set to %20 before the 'é' gets converted, but then becomes %20%A9 afterwards. As if the %A9 of my 'é' stays in the buffer and breaks my encoding of space character.

Any help would be appreciated I am not even dealing with XML processing of the reply for webservice as I cannot get the query going :)

Thanks, Stephane
