It might be useful to represent non-UTF-8 bytes as Unicode code points. One way might be to use a codepoint to indicate high bit set followed by the byte value with its high bit set to 0, that is, truncated into the ASCII range. For example, U+0080 looks like it is not in use, though I could not verify this.
