#101 WikiPage with certain chars are broken

[Anonymous]

If a WikiPage has a name containing either a number or an underscore
the BackLinks do not work. I checked the database queries ( mysql )
and saw that TN.TE.MigrateTo230 becomes TN.TE.MigrateTo.
Since that page does not exist the backlink stay empty.

Page access to that particular page works ok. The bug
does not seem to be in the database backends
( verified against 1.3.2 )

Version: 1.3.3
Mysql: Ver 3.23.49 for pc-linux-gnu on i686
PHP: 4.1.1-2

The error is actually caused by a 'too-aggresive' footnote
deletion regexp in the function ExtractWikiPageLinks

I think that part of the code needs a little rewrite

Replace
// remove footnotes
$line = preg_replace('/[[\d+]/', ' ',
$line);
with
// remove footnotes
$line =
preg_replace('/[[\d+]/', ' ', $line);

in stdlib.php

That regexp needs to be changed anyway, as it won't
successfully delete footnotes with more than one digit.
(Although it will delete the footnote [+])

WikiPages containing spaces also break the BackLinks code,
but that seems to be a different bug...?

works now even with "0" as pagename.
