I had no answer to my question,
but the problem is still there and quite bothering.
Every time I save a page in which there is a link to a page which name contains an apostroph, then the wiki automatically modify the name of this page. It ad a _ before the apostroph. What is silly, is that next time I save this page again, it ads an another _.
After a few time, the page name contains 4 or 5 _ !
For exemple, "EDF s'oppose aux ENR" becomes "EDF s'___oppose aux ENR".
Am I the only personn to get thoses troubles ?
Any idea to prevent this problem ?
This occurs since we've updated to Moodle versions : 1.9.4
