That Chris Glur is an idiot.

  $ echo -e "\xe2\x80" > magic-quote
  $ xxd magic-quote
  0000000: e280 0a
  $ cp magic-quote magic-quote2
  $ grep $'\xe2' magic-quote*
  magic-quote:â€
  magic-quote2:â€

Grep works just fine with any character you give it to search (other
than maybe an ASCII null).  But first, you have to type the characters
into the shell in such a way that Bash understands your meaning.  You
can not directly type a \xe2 character (well, not easily) from the
keyboard.  So you have to tell Bash "this next thing is a special
character".  That is what the $'\xe2' piece does.  It tells Bash "this
next thing is a special character that can't be directly typed on the
keyboard".

The problem, as always, was your failure to understand.
