sorry to bother with special characters again, but when using a single quote in blog's title ("JP's blog"), the subject of notifications emails look like that (I removed the leading & so that it is not interpreted by the forum form) :
[JP#039;s blog] FAIL for dsdzsf
and in the body :
Failed login at JP#039;s blog by dsdzsf (21:55:57.8719)
It seems to work fine with special characters like "é".
