Description Petr Pisar 2011-11-24 09:08:42 UTC 
From upstream <http://bugs.exim.org/show_bug.cgi?id=1179>:

$ pcretest 
PCRE version 8.12 2011-01-15

  re> /ⱥ/8i
data> ⱥ
 0: \x{2c65}
data> Ⱥ
No match
data> Ⱥ_
 0: \x{23a}

The lower-cased variant occupies 3 bytes while the upper-cased variant 2 bytes only. If padding in input exists, the match occurs.
