/*
  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.

  Some notes about the following comparison rules:
  By definition, my_strnncoll_latin1_de() must work exactly as if one had called

  This means that Ä must also match ÁE and Aè, because my_strxnfrm_latin1_de()
  will convert both to AE.

  The other option would be to not do any accent removal in
  sort_order_latin_de[] at all.
