Ortwin Glück resolved HTTPCLIENT-642.
-------------------------------------
Resolution: Invalid
Ralf,
You have a form that accepts ISO-8859-1. But then your user enters a chinese
character which CAN NOT be represented in that encoding. That's why your
browser resorts to representation as an HTML entity: "能" which it
additionally HTML-encodes to "能". I know of no standard that
describes this behviour. It looks completely arbitrary. As a matter of fact,
entering of non-ISO characters in such a form is not allowed and the result is
not well-defined. If you need chinese characters use a UTF-8 capable form.
Now, in your example the url variable contains a # character which is NOT used
as a separater for the reference (anchor) part of the URL. The # character is a
reserved URI character for that purpose. So it must be escaped when used
inside a GET parameter value like in this example. This means that this URL is
not properly escaped. The URI class' behaviour is correct.

> a mozilla 1.5.0.10 get request of an iso-8859-1 form where a user
> inadvertently entered a chinese character arrives at my tomcat like
> String url= "/hp/index.php?address=addr&[EMAIL
> PROTECTED]&name=Ralf能 GMX&subject=Newsletter"
> the chinese charcter 能 being encoded as 能
> URI uri = new URI(url, false, "ISO-8859-1");
> GetMethod httpGet = new
> GetMethod(uri.getEscapedURI());
> log.debug(httpGet.getURI());
> "/hp/index.php?address=addr&[EMAIL PROTECTED]&name=Ralf&"
> How should I deal with that until the v4 is out? Will that no longer happen
> there?
