I've filed a bug report against the PEAR package:



http://pear.php.net/bugs/bug.php?id=15385



A temporary workaround would be to change line 134 of Wikilink.php to:



$href = sprintf(substr_replace($href, ereg_replace("%", 
"%%",substr($href, strpos($href, '%')+1)),strpos($href, 
'%')+1),$this->urlEncode($page));



This will cause every % sign after the first one to be escaped (%%).

The bug is in text_wiki, a PEAR package, not in Wicked.

The trouble is not with the page I attached.



The problem is the "referrer" or "page name". I was using "Tributário" 
in the previous page, like this:



[[Tributário]]



Then, when you click on it, it turns to "Tribut%C3%A1rio" and the 
sprintf lines get like this:



sprintf(/wicked/display.php?page=%s&referrer=Tribut%C3%A1rio, 
Parcelamento_Generico);



(Line 134 - /usr/share/pear/Text/Wiki/Render/Xhtml/wikilink.php)



Then, I think php complains about the lack of arguments due to the "%" 
signs...



If I use "Tributario" instead of "Tributário" as the page name, then 
it works...



In other words, I can´t create wiki links with special characters like 
á, é, ó etc., because the wiki links on the created pages will be broke.



I don´t know if it´s not a wicked issue and I´m sorry in advance if 
this is the case. Please provide orientation so I can report the bug 
on the right place.



Thanks

Attached is the page generating the warnings.

It´s actually preventing me from opening internal links now.



I´m getting the same warning 12 times when I click on a internal link 
and instead of being asked to create the page, I return to the same 
page.



I´m using MediWiki as [wicked][format].

Horde: 3.3.3-cvs

Wicked: 1.0-cvs



This happens when I edit a page and click "save":



( ! ) Warning: sprintf() [function.sprintf]: Too few arguments in 
/usr/share/pear/Text/Wiki/Render/Xhtml/Wikilink.php on line 134
