Bug#561751: elinks doesn't handle URIs with non-ASCII characters correctly

Sat, 19 Dec 2009 19:55:37 -0800 

Package: elinks
Version: 0.12~pre5-1
Severity: normal

With the first attached file, the first two URIs are not handled
correctly: the "è" character is replaced by %E8 instead of %C3%A8
as required by the XML spec (so that the document isn't found):

  http://www.w3.org/TR/xmlschema-2/#anyURI
  http://www.w3.org/TR/xlink/#link-locators

Note: It is not clear whether non-ASCII characters are allowed in
XHTML 1.0: they are allowed in XML and the document validates, but
they are forbidden in HTML 4. Anyway the HTML 4 spec says how they
should be handled (i.e. in the same way as in XLink):

  http://www.w3.org/TR/html4/appendix/notes.html#non-ascii-chars

Everything works fine with the second file. This shows that elinks
uses the encoding of the document to decide what to do (which is
bad).

Also note that in both files, NFD doesn't work, but I assume that's
a problem with the XLink spec and/or the web server (really, when
typing a URL, the user shouldn't care whether an accented character
is represented using NFC or NFD).
