Behdad Esfahbod 351cccdb75 [buffer-deserialize] Deserialize glyph flags 
Fixes https://github.com/harfbuzz/harfbuzz/issues/1482

Behdad Esfahbod 5134041f21 [deserialize-json] Make it actually work! 
Was not correctly deserializing glyph names as it was not dropping
double-quotes from glyph name before parsing.

Behdad Esfahbod 5ef0613909 [buffer] Add ensure_glyphs()/ensure_unicode() 
Use in deserialize. To be used more.

Behdad Esfahbod b37edebfcb [buffer/deserialize] Do not clear() buffer upon content type mismatch 
We return false. I don't see reason to clear buffer.

Behdad Esfahbod c396e1600f [buffer/deserialize] Accept arbitrary glyph names 
Accepts escapes. Added TODO items for matching escaping in serialize().

Behdad Esfahbod 4a4eebcf86 [buffer/serialize] Minor renames in Ragel machines

Simon Cozens 150f391438 Prohibit mixed glyphs/unicode buffers in deserialization 2020-10-09 22:27:55 -06:00
Simon Cozens 3d3c87e7e7 Put the flags back in and serialize clusters. 
Note that now JSON glyph buffers and Unicode buffers look very similar, except for the g/u property difference.

Behdad Esfahbod ae8719eb59 [ragel] Switch to -T1 output instead of -F1 
Fedora upgraded to ragel 7, which is buggy if char is signed.
Switching to -G2 output fails with sign-compare error:

../../src/hb-buffer-deserialize-json.hh:107:12: error: comparison of integer expressions of different signedness: ‘unsigned int’ and ‘const char’ [-Werror=sign-compare]
    if ( 9u <= ( (*( p))) && ( (*( p))) <= 13u ) {
         ~~~^~~~~~~~~~~~~

Switching to -T1 for now.  It actually results in smaller code,
at the expense of some binary searching instead of flat tables.
In the not distant future, we might actually generate two different
outputs and choose between depending on size-optimize options.

Sorry for the noise, downstream custom builders.  Please adjust.
