Confusion

口 (X53E3) is highly confusional character. Even a native Japanese speaker, looking at characters
⼝, ⼞, ロ, 口, ﾛ, cannot answer:
which of them is X2F1D (KanjiRadical)?
which of them is X2F1E (KanjiRadical)?
which of them is X30ED (Katkana "ro")?
which of them is X53E3 (KanjiLiberal)?
which of them is XFF9B ( Character from the UnicodeBottom table)?

The manuals on Japanese, as well as dictionaries (Jishos) usually ignore this confusion.
Those, who learn Japanese, have to investigate such a cases by themselves.

Only one of the 5 characters, 口, X53E3, is qualified as KanjiLiberal.
Perhaps, namely this character should be used for generation of Japanese texts.
