Usually we say the word is actually refers to the character, the character refers to the computer use of letters, numbers, words and symbols, including: 1, 2, 3, A, B, C, ~! #￥%......-* ()--+ and so on.The characters in different encoding formats are different, such as 2 bytes in GBK, 3 bytes in Utf-8, and iso8859-1 strictly for Chinese characters. Utf-8 is only an implementation of the
