<p><b>Byte-oriented framing protocol</b> is "a communications protocol in which full bytes are used as control codes. Also known as character-oriented protocol."<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> For example <a href="UART" class="mw-redirect" title="UART">UART</a> communication is byte-oriented.
</p><p>The term "character-oriented" is deprecated, since the notion of character has changed. An ASCII character fits to one byte (octet) in terms of the amount of information. With the internationalization of computer software, wide characters became necessary, to handle texts in different languages. In particular, Unicode characters (or strictly speaking <a href="Code_point" title="Code point">code points</a>) can be 1, 2, 3 or 4 bytes in <a href="UTF-8" title="UTF-8">UTF-8</a>, and other encodings of <a href="Unicode" title="Unicode">Unicode</a> use two or four bytes per code point.
