A single symbol of Kanji. Japanese Kanji were borrowed from China over several waves during the last 1,500 years. Japan names 2,136 of these as their standard set, with rarer characters being the domain of academia and esoteric writers.

Japanese has several Japan-only Kanji, including:

• 畑 (a type of rice field)
• 峠 (a narrow mountain pass)
• 働 (to do physical labour)

The original Char of a Kanji.

Construct a Kanji value from some Char if it falls in the correct UTF8 range.

A Level or Kyuu (級) of Japanese Kanji ranking. There are 12 of these, from 10 to 1, including intermediate levels between 3 and 2, and 2 and 1.

Japanese students will typically have Level-5 ability by the time they finish elementary school. Level-5 accounts for 1,006 characters.

By the end of middle school, they would have covered up to Level-3 (1607 Kanji) in their Japanese class curriculum.

While Level-2 (2,136 Kanji) is considered "standard adult" ability, many adults could not pass the Level-2, or even the Level-Pre2 (1940 Kanji) exam without considerable study.

Level data for Kanji above Level-2 is currently not provided by this library.

Legal Kanji appear between UTF-8 characters 19968 and 40959.
