Does not support writing in both Chinese and English. Even if there is a space in the middle, it won’t work. The limit on the number of characters is 6 characters in Chinese, and 12 letters in English, which is not case-sensitive. Because a Chinese character has two bytes per character, there are only 6 characters!
Nowadays, some people want to make their names more personalized, so they can only use the Wubi input method to input radicals, which is allowed!
