I try to create a link to my email address and got a trouble due to the fact that it contains a dot between my name and surname (eric.bacquet@…) This address seems to be a problem for the function obfuscateEmails($str) in the core file view.php. I changed the regex in the function by this one
and my link works correctly now. I'm not sure that this regex is something great but it solved my case.
There are just hundreds of patterns for that :-(
