CJK characters
Chinese is written almost exclusively in Chinese characters. It requires over 3,000 characters for general literacy, but up to 40,000 characters for reasonably complete coverage. Japanese uses fewer characters — general literacy in Japanese can be expected with 1,945 characters. The use of Chinese characters in Korea is becoming increasingly rare, although idiosyncratic use of Chinese characters in proper names requires knowledge (and therefore availability) of many more characters. However, even today, students in South Korea are taught 1,800 characters.
Kangxi Dictionary
The supplemented dictionary contains 47,035 character entries, plus 1,995 graphic variants, giving a total of 49,030 different characters. They are grouped under the 214 radicals and arranged by the number of additional strokes in the character. Although these 214 radicals were first used in the "Zihui", due to the popularity of the "Kangxi Dictionary" they are known as Kangxi radicals and remain in modern usage as a method to categorize traditional Chinese characters.
