Questions tagged [utf-8]

UTF-8 is a multibyte character encoding of the Unicode character set, made up of one or more bytes. Unlike some other encodings such as UTF-16, the UTF-8 encoding is upward compatible with 7-bit ASCII characters, and can be processed to some degree by applications that are only aware of bytes.
