--- Japanese students will typically have Level-5 ability by the time they
--- finish elementary school. Level-5 accounts for 1006 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 (2136 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.
