鬪 - 鬦 - 闘 - 閗), some of which are considered the older forms of Chinese characters and variations of different Chinese regions, and the older forms of Japanese characters (kyūjitai). Traditional characters that may cause problems displaying Note that within the kyōiku kanji, there are 26 characters; the old forms of which may cause problems displaying: Grade 2 (2 kanji): 海 社 Grade 3 (8 kanji): 勉 暑 漢 神 福 練 者 都 Grade 4 (6 kanji): 器 殺 祝 節 梅 類 Grade 5 (1 kanji): 祖 Grade 6 (9 kanji): 勤 穀 視 署 層 著 諸 難 朗 Within the jōyō kanji, the same is true for 36 secondary-school kanji, so, in total, 62 of the 2,136 jōyō kanji have traditional forms that may cause problems displaying. These characters are Unicode CJK Unified Ideographs for which the old form (kyūjitai) and the new form (shinjitai) have been unified under the Unicode standard. Although the old and new forms are distinguished under the JIS X 0213 standard, the old forms map to Unicode CJK Compatibility Ideographs which are considered by Unicode to be canonically equivalent to the new forms and may not be distinguished by user agents. Therefore, depending on the user environment, it may not be possible to see the distinction between old and new forms of the characters. In particular, all Unicode normalization methods merge the old characters with the new ones. List of the simplified kyōiku kanji For example, 万 is the simplified form of 萬.
