[pmwiki-users] Issue with blocklist regex (for /\bcialis\b/), blocking word spécialisé

[ABClf]

Hello,

Not a big issue, but a strange one : my blocklist has an entry copied
from PmWiki's :

block:/\bcialis\b/

This wrongly blocks the word "spécialisé" on my website whereas
everything is fine in PmWiki, where "spécialisé" is allowed, as
expected.
(Can check the issue in www.languefrancaise/Test group).

Does anyone have an idea why I encounter such an issue ? It looks like
the boundaries of the regex (only block full word) is not well
interpreted on my host. (Yet it should be working :
http://www.languefrancaise.net/phpinfo.php)

In top of my config :
$EnableBlocklist           = 1;          # This tells PmWiki to scan
the SiteAdmin.Blocklist page and the SiteAdmin.Blocklist-Farm
$EnableWhyBlocked          = 1;

Gilles.
