Lingua::ZH::HanDetect uses statistical measures to test a text string
to see if it's in Traditional or Simplified Chinese, as well as which
encoding it is in.

If the string does not contain Chinese characters, both the encoding
and variant values will be set to the empty string.

This module is needed because the various encodings for Chinese text
tend to occupy the similar byte ranges, rendering Encode::Guess
ineffective.
