A character set is a set of characters, and alphabets, hiragana, kanji, etc. are examples of character sets. Currently, in order to facilitate the exchange of character information, a set of characters that can be used on a computer is defined as a character set in each industry standard or international standard. For example, the character code system that represents a Japanese character set is JIS90 and JIS2004 are typical examples.

A variant character is a set of characters having the same meaning and reading but different shapes, such as old characters and new characters, and characters having different character shapes although they are equivalent characters.
For example, as shown in FIG. 3, the character code 3652 is a character code of “辻”, and “辻” has “one-point Shin-no-i” and “two-point Shin-no-i”, meaning and reading It is a set of characters that are the same but have different shapes. In FIG. 3, a character set of “one-point Shin-no-an” is assigned to JIS 90, and “two-point Shin-no-an” is assigned to JIS 2004.
