What is utf8

UTF-8 (8 bits, Universal Character Set/Unicode Transformation Format) is A variable-length character encoding for Unicode. It can be used to represent any character in the Unicode standard, and the first byte in its encoding is still compatible with ASCII, so that the original software that processes ASCII characters can continue to be used without or with only a few modifications. Therefore, it has gradually become the preferred encoding for email, web pages, and other applications that store or transmit text.
