Non-breaking space in all its forms should be rendered as
(working with all browsers I'm aware of) or (issues with
one old browser if there are two or more adjacent ).
Under absolutely no circumstances can /   /
or the corresponding UTF-8 be rendered as mere SP, that causes
havoc. This appears to be relatively new (2006-04-13 maybe?).
I've tested it elsewhere with action=render, it's no skin issue.
Whatever it is, it's not everywhere.
I've tracked it down in http://en.wikipedia.org/wiki/User:Omniplex/5569
Theory: On a page with <pre>...</pre> later occurences of
nbsp or #160 are translate to a space. An empty <pre></pre>
doesn't have this side-effect.
The example was in a discussion about another <pre> oddity
at the bottom of:
Something with <pre> is odd. And that's not new, I always
(this year) avoided it, because it doesn't behave like a
normal XHTML <pre>.
Please provide example input and output, clearly labeled.
Broken after <pre> </pre>:
Okay after <pre></pre>:
JFTR I added an example for the other <pre> oddity,
where it affects text on the same line before <pre>:
Probably a bug in tidy. Can reproduce locally only with tidy enabled.

This hits me about once per day, and there's absolutely no workaround,
therefore I mark it as "serious". It's easy to avoid all <pre>
and Wiki "space in column one" on a new page, but a PITA on old pages
if I want to work as designed.
It breaks my signature. It breaks templates like Tlx and Tlsp. It breaks
dummy table cells.

test case to reproduce the problem with tidy on the command line
I can verify the bug (directly on the command line) with the tidy version "HTML
Tidy for Linux/x86 released on 1st March 2004": After the <pre>-block, all
are replaced by regular space. This is fixed in newer versions of tidy:
the problem is gone in version "HTML Tidy for Linux/x86 released on 1 September
This breaks <poem> tags too (see [[s:en:Help:Editing poetry]]).
This is because Tidy hasn't been updated, not a MediaWiki problem. MediaWiki ->
This bug breaks pages and templates on Dutch WP too: [[s:nl:Gebruiker:Erik
The problem seems to have disappeared; see
Should have been fixed by Tim upgrading Tidy.
