Character.isSurrogatePair介绍

[英]Indicates whether the specified character pair is a valid surrogate pair.
[中]指示指定的字符对是否为有效的代理项对。

 * Checks whether a given String consists only of surrogate pairs.
 * @param word to be checked
 * @since 4.2
 */

  // some symbols such as emojis (😂) have a string length that equals 2
  boolean isSurrogatePairCombination = true;
  for (int i = 0; i < word.length() && isSurrogatePairCombination; i += 2) {
   isSurrogatePairCombination &= Character.isSurrogatePair(word.charAt(i), word.charAt(i + 1));
  }
