# additions to class String for Unicode normalization
class String
  # === Unicode Normalization
  #
  # :call-seq:
  #    str.unicode_normalize(form=:nfc)
  #
  # Returns a normalized form of +str+, using Unicode normalizations
  # NFC, NFD, NFKC, or NFKD. The normalization form used is determined
  # by +form+, which is any of the four values :nfc, :nfd, :nfkc, or :nfkd.
  # The default is :nfc.
  #
  # If the string is not in a Unicode Encoding, then an Exception is raised.
  # In this context, 'Unicode Encoding' means any of  UTF-8, UTF-16BE/LE,
  # and UTF-32BE/LE, as well as GB18030, UCS_2BE, and UCS_4BE. Anything
  # else than UTF-8 is implemented by converting to UTF-8,
  # which makes it slower than UTF-8.
  #
  # _Examples_
  #
  #   "a\u0300".unicode_normalize        #=> 'à' (same as "\u00E0")
  #   "a\u0300".unicode_normalize(:nfc)  #=> 'à' (same as "\u00E0")
  #   "\u00E0".unicode_normalize(:nfd)   #=> 'à' (same as "a\u0300")
  #   "\xE0".force_encoding('ISO-8859-1').unicode_normalize(:nfd)
  #                                      #=> Encoding::CompatibilityError raised

  # The default is :nfc.
