Zhon's constants can be used in Chinese text processing, for example:

• Find CJK characters in a string:

  >>> re.findall('[{}]'.format(zhon.hanzi.characters), 'I broke a plate: 我打破了一个盘子.')
  ['我', '打', '破', '了', '一', '个', '盘', '子']

• Validate Pinyin syllables, words, or sentences:

  >>> re.findall(zhon.pinyin.syllable, 'Yuànzi lǐ tíngzhe yí liàng chē.', re.I)
  ['Yuàn', 'zi', 'lǐ', 'tíng', 'zhe', 'yí', 'liàng', 'chē']
  
  >>> re.findall(zhon.pinyin.word, 'Yuànzi lǐ tíngzhe yí liàng chē.', re.I)
  ['Yuànzi', 'lǐ', 'tíngzhe', 'yí', 'liàng', 'chē']
  
  >>> re.findall(zhon.pinyin.sentence, 'Yuànzi lǐ tíngzhe yí liàng chē.', re.I)
  ['Yuànzi lǐ tíngzhe yí liàng chē.']
