1. Every ASCII character that can appear in a well-formed XML document,

must be represented by a single byte, and that byte must be the

same byte that represents that character in ASCII.

2. No character may require more than 4 bytes to encode.
|
|
|
|
3. All characters encoded must have Unicode scalar values <= 0xFFFF,
|
|
(ie characters that would be encoded by surrogates in UTF-16
|
|
are not allowed). Note that this restriction doesn't apply to
|
|
the built-in support for UTF-8 and UTF-16.

4. No Unicode character may be encoded by more than one distinct sequence

of bytes. */
