Ignorance

Many manuals of Japanese Kanjis ignore confusion of character ⽇ with 3 other Nichi kanjis.

Even a native Japanese speaker, looking at characters ⽇ ⽈ 日 曰, is unlikely to answer:
Which or them is X2F47 ?
Which or them is X2F48 ?
Which or them is X65E5 ?
Which or them is X66F0 ?

Various sites, dedicated to Japanese Kanji (including Jisho and Nihongomaster) do not explain meaning of some of the Nichi characters, ignore the similarity of the Nichi characters.

Some sites mention the semihance of ⽇ with other characters .

The abuse of encoding, as well as the unwanted misprints (some unusual, unexpected kanji with similar picture) make serious problems in the handling of data and processing of texts, in particular, at the searching and the replacement. The revealing of the encoding by program du.t helps to detect, recognize the errors and to correct them.
