-/* Lookup table to map the previous two bytes to a context id.
-
- There are four different context modeling modes defined here:
- CONTEXT_LSB6: context id is the least significant 6 bits of the last byte,
- CONTEXT_MSB6: context id is the most significant 6 bits of the last byte,
- CONTEXT_UTF8: second-order context model tuned for UTF8-encoded text,
- CONTEXT_SIGNED: 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 CONTEXT_UTF8 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 |
- |-------------|-------------------|---------------------|------------------|
- | cont. byte | next: ASCII/lead | next: ASCII/lead | next: cont. |
- | (128-191) | context: 4 - 63 | context: 0 - 1 | context: 2 - 3 |
- |-------------|-------------------|---------------------|------------------|
- | lead byte | not valid | next: ASCII/lead | not valid |
- | (192-207) | | context: 0 - 1 | |
- |-------------|-------------------|---------------------|------------------|
- | lead byte | not valid | next: cont. | not valid |
- | (208-) | | context: 2 - 3 | |
- |-------------|-------------------|---------------------|------------------|
