How many bytes does each character need to be stored using UTF-8?

UTF-8 is based on 8-bit code units. Each character is encoded as 1 to 4 bytes. The first 128 Unicode code points are encoded as 1 byte in UTF-8.

Does UTF-8 require a byte order mark?

The Unicode Standard permits the BOM in UTF-8, but does not require or recommend its use. Byte order has no meaning in UTF-8, so its only use in UTF-8 is to signal at the start that the text stream is encoded in UTF-8, or that it was converted to UTF-8 from a stream that contained an optional BOM.
