+
+   The map[b] member gives information about byte sequences whose
+   first byte is b.
+
+   If map[b] is c where c is >= 0, then b by itself encodes the
+   Unicode scalar value c.
+
+   If map[b] is -1, then the byte sequence is malformed.
+
+   If map[b] is -n, where n >= 2, then b is the first byte of an
+   n-byte sequence that encodes a single Unicode scalar value.
+
+   The data member will be passed as the first argument to the convert
+   function.
+
+   The convert function is used to convert multibyte sequences; s will
+   point to a n-byte sequence where map[(unsigned char)*s] == -n.  The
+   convert function must return the Unicode scalar value represented
+   by this byte sequence or -1 if the byte sequence is malformed.
+
+   The convert function may be NULL if the encoding is a single-byte
+   encoding, that is if map[b] >= -1 for all bytes b.
+
+   When the parser is finished with the encoding, then if release is
+   not NULL, it will call release passing it the data member; once
+   release has been called, the convert function will not be called
+   again.
+
+   Expat places certain restrictions on the encodings that are supported
+   using this mechanism.
+
+   1. Every ASCII character that can appear in a well-formed XML document,
+      other than the characters
+
+      $@\^`{}~
+
+      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, (i.e., 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.
