title: Can a line feed (hexadecimal 0x0A) be legally embedded in UTF8?
body: <p>I'm designing a simple file format, and instead of supporting only extended US ASCII, I was thinking of supporting UTF8.</p>
  
  <p>The line feed byte (hexadecimal 0x0A) is one of the delimiters. Is it possible for this byte sequence to be embedded in a multi-byte UTF8 sequence? E.g., where one of the initial bytes has the high bit set (indicating a multi-byte character) and one of the trailing bytes is 0x0A?</p>
