Hi, I have run into a bug in the ListPages module on our wiki.

One of the pages on our wiki has the title

.::Only |n Drea{{m}}s--

with the filename

only-in-dreams

Whenever the page appears in any of the ListPages listings (e.g. system:list-all-pages), all that's shown is something like

.::Only |n Drea{{m}}s--

This is with the use of the %%title_linked%% variable.

The best temporary fix I have right now is to replace the %%title_linked%% variable with [http://path/to/wiki/%%fullname%% %%title%%] which got around the issue but it is still an ugly hack. Plus, now all the titleless pages are now showing up as:

e.g. [http://path/to/wiki/system:pagename ]

because a hyperlink bracket-block doesn't accept the empty string as a valid link label.

I was wondering if either
a) Page titles can be escaped in ListPages to avoid errors
b) A new variable be implemented that would maybe escape the special characters in a title so that ListPages won't break when special characters are used in a page's title. Maybe call it %%safe_title_linked%%.

The lack of proper input sanitization is also a big concern…

On the other hand, the RecentChanges module does not have this issue.
