/* Lookup table to map the previous two bytes to a context id.
|
||
|
|
||
|
There are four different context modeling modes defined here:
|
||
|
contextLSB6: context id is the least significant 6 bits of the last byte,
|
||
|
contextMSB6: context id is the most significant 6 bits of the last byte,
|
||
|
contextUTF8: second-order context model tuned for UTF8-encoded text,
|
||
|
contextSigned: second-order context model tuned for signed integers.
|
||
|
|
||
|
If |p1| and |p2| are the previous two bytes, and |mode| is current context
|
||
|
mode, we calculate the context as:
|
||
|
|
||
|
context = ContextLut(mode)[p1] | ContextLut(mode)[p2 + 256].
|
||
|
|
||
|
For contextUTF8 mode, if the previous two bytes are ASCII characters
|
||
|
(i.e. < 128), this will be equivalent to
|
||
|
|
||
|
context = 4 * context1(p1) + context2(p2),
|
||
|
|
||
|
where context1 is based on the previous byte in the following way:
|
||
|
|
||
|
0 : non-ASCII control
|
||
|
1 : \t, \n, \r
|
||
|
2 : space
|
||
|
3 : other punctuation
|
||
|
4 : " '
|
||
|
5 : %
|
||
|
6 : ( < [ {
|
||
|
7 : ) > ] }
|
||
|
8 : , ; :
|
||
|
9 : .
|
||
|
10 : =
|
||
|
11 : number
|
||
|
12 : upper-case vowel
|
||
|
13 : upper-case consonant
|
||
|
14 : lower-case vowel
|
||
|
15 : lower-case consonant
|
||
|
|
||
|
and context2 is based on the second last byte:
|
||
|
|
||
|
0 : control, space
|
||
|
1 : punctuation
|
||
|
2 : upper-case letter, number
|
||
|
3 : lower-case letter
|
||
|
|
||
|
If the last byte is ASCII, and the second last byte is not (in a valid UTF8
|
||
|
stream it will be a continuation byte, value between 128 and 191), the
|
||
|
context is the same as if the second last byte was an ASCII control or space.
|
||
|
|
||
|
If the last byte is a UTF8 lead byte (value >= 192), then the next byte will
|
||
|
be a continuation byte and the context id is 2 or 3 depending on the LSB of
|
||
|
the last byte and to a lesser extent on the second last byte if it is ASCII.
|
||
|
|
||
|
If the last byte is a UTF8 continuation byte, the second last byte can be:
|
||
|
- continuation byte: the next byte is probably ASCII or lead byte (assuming
|
||
|
4-byte UTF8 characters are rare) and the context id is 0 or 1.
|
||
|
- lead byte (192 - 207): next byte is ASCII or lead byte, context is 0 or 1
|
||
|
- lead byte (208 - 255): next byte is continuation byte, context is 2 or 3
|
||
|
|
||
|
The possible value combinations of the previous two bytes, the range of
|
||
|
context ids and the type of the next byte is summarized in the table below:
|
||
|
|
||
|
|--------\-----------------------------------------------------------------|
|
||
|
| \ Last byte |
|
||
|
| Second \---------------------------------------------------------------|
|
||
|
| last byte \ ASCII | cont. byte | lead byte |
|
||
|
| \ (0-127) | (128-191) | (192-) |
|
||
|
|=============|===================|=====================|==================|
|
||
|
| ASCII | next: ASCII/lead | not valid | next: cont. |
|
||
|
| (0-127) | context: 4 - 63 | | context: 2 - 3 |
|
||
|
|-------------|-------------------|---------------------|------------------|
|
||
|
