Unwelcomed Default Change in Mail.app

Recently I received a message from a friend, who has just switched to a
Macintosh, and I've become his Mac support. In the part of his message,
quoted below, you can see his problem with Mail.app. I've never had this
happen to me, so I don't know how to fix this matter. Can someone advise
me what I should tell him how what he should do? TIA

Looks to me like your friend is used to mashing his fingers on the
keyboard in certain ways to produce certain non-ASCII characters, and
the Mac uses different mashes than he's used to.

Opt-[ = ³ (double-left)
Opt-Shift-[ = ² (double-right)
Opt-] = Π(single-left)
Opt-Shift-] = ¹ (single-right)

"Congurutulation!!!" - The subject line on some spam I received recently.
I have no idea what it means, but it's such a cool "word" (by which I mean
pronouncable sequence of letters) regardless.
