I noticed that an apostrophe in a page name sometimes breaks the
{action name="edit"} feature. specifically, when logged in as
editor and with an {if permit="editable"} block added to the left or
right column, an {action name="edit"} for a page with an
apostrophe in it will not work correctly, but will try to edit a page
with a name based on the characters before the apostrophe.
EXAMPLE:
you have a page name [[I'm_a_Bad_Page]]
(I use free links, so I'm not sure if it happens with WikiWords)
when you click on an edit action link embedded in a
permit=editable block, it tries to edit the page named [[I]]
when you click on the "Edit This Page" link in the page footer, it
edits the correct page [[I'm_a_Bad_Page]]
