   * variable characters in the UCA: whitespace, punctuation and symbols. If
   * Alternate is set to NonIgnorable
   * (N), then differences among these characters are of the same importance
   * as differences among letters. If Alternate is set to
   * Shifted
   * (S), then these characters are of only minor importance. The
   * Shifted value is often used in combination with
   * Strength
   * set to Quaternary. In such a case, whitespace, punctuation, and symbols
   * are considered when comparing strings, but only if all other aspects of
   * the strings (base letters, accents, and case) are identical. If
   * Alternate is not set to Shifted, then there is no difference between a
   * Strength of 3 and a Strength of 4. For more information and examples,
   * see Variable_Weighting in the
   * UCA.
   * The reason the Alternate values are not simply
   * On and Off
   * is that additional Alternate values may be added in the future. The UCA
   * option Blanked is expressed with Strength set to 3, and Alternate set to
   * Shifted. The default for most locales is NonIgnorable. If Shifted is
   * selected, it may be slower if there are many strings that are the same
   * except for punctuation; sort key length will not be affected unless the
   * strength level is also increased.
