I've been learning kanji from a few different resources (internet, books, etc). For example, in some sources, the kanji ナ?L is said to have one kun reading (kai) and no on reading. But, another source will say that it does have an on reading (bai). Another example is the kanji 窶ーツコ. Some source tells me it has three kun readings when another source lists around 12 readings. How do I know if what I'm learning is the real deal?
Thank you in advance.
