But it gets to Zope via HTTP, which is an ASCII subset.  The publisher
is supposed to give all of this to Zope decoded.  IOW, the input data
to getApplicationURL should always be unicode.  I guess getApplicationURL
encodes. (? I don't remember the details.)

Hm, the interface for getApplicationURL doesn't say whether the returned
value is encoded. It needs to say this.  The interface needs to be fixed
IOW.

Given:

- We expect a URL

- URLs must be URL encoded

- *Before* URL encoding, we need to utf-8 encode

Then the output of getApplicationURL must certainly be a utf-8-url-encoded
string.

That would be great!
