to the parser.
|
||
|
|
||
|
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.
