What Ruby version?  Can you show the exact code to build the string 
test12?  It works for me even on 1.8:

$ irb
irb(main):001:0> s=<<STR
irb(main):002:0" foo
irb(main):003:0" bar
irb(main):004:0" person@cogeco.ca
irb(main):005:0" baz
irb(main):006:0" STR
=> "foo\nbar\nperson@cogeco.ca\nbaz\n"
irb(main):007:0> s.include? "person@coge"
=> true
irb(main):008:0> s.include? "person@cogec"
=> true
irb(main):009:0>

I suggest to print the string with p to discover control characters you 
might have in there.

Kind regards
