public bool iswide_cjk ()

Determines if a character is typically rendered in a double-width cell under legacy East Asian locales.

If a character is wide according to iswide, then it is also reported wide with this function, but the converse is not necessarily true. See the Unicode Standard Annex #11 for details.

If a character passes the iswide test then it will also pass this test, but not the other way around. Note that some characters may pass both this test and iszerowidth .
