/*
  WL#1494 notes:
  
  We'll use cp1252 instead of iso-8859-1.
  cp1252 contains printable characters in the range 0x80-0x9F.
  In ISO 8859-1, these code points have no associated printable
  characters. Therefore, by converting from CP1252 to ISO 8859-1,
  one would lose the euro (for instance). Since most people are
  unaware of the difference, and since we don't really want a
  "Windows ANSI" to differ from a "Unix ANSI", we will:
   
   - continue to pretend the latin1 character set is ISO 8859-1
   - actually allow the storage of euro etc. so it's actually cp1252

  Also we'll map these five undefined cp1252 character:
    0x81, 0x8D, 0x8F, 0x90, 0x9D
  into corresponding control characters:
     U+0081, U+008D, U+008F, U+0090, U+009D.
  like ISO-8859-1 does. Otherwise, loading "mysqldump"
  output doesn't reproduce these undefined characters.
