Confusion and Tarja

Character X5FC3 心 ^[1] is easy to confuse with
character X2F3C ⼼ ^[2]. These characters have similar pictures, similar semantic and similar pronunciation.

Even a native Japanese speaker, looking at characters ⼼, 心 is unlikely to guess:
Which of them is character number X2F3C?
Which of them is character number X5FC3?

For this confusion, neither ⼼ nor 心 are allowed in Tarja - until the common bugs in the softwares are corrected and each of these characters gets unique exclusive default picture at the most of software used to deal with the Unicode characters, to show them at a screen, to print them in a form that allows their identification.

While the confusion remains. At the translation from Japanese to Tarja, characters ⼼ and 心 can be replaced to explicit indications of their hexadecimal numbers X2F3C and X5FC3. (Anyway, looking at the Kanji, one cannot deduce its pronunciation; the pronunciation should be guessed from the context).

Also, ⼼ and 心 can be replaced to the transliteration to Hiragana or Romaji, according to the context.

Also, at the translation to Tarja, ⼼ and 心 can be replaced to its English equivalent, following suggestions by Jisho, Nihongomaster, Unicode Utilities and/or the automatic translators. (Choosing the English analogy most suitable for the context.)

Such a translation is supposed to exclude the confusion mentioned from any text that use the ambiguous Kanjis (those that are not yet supplied with unique exclusive pictures).
