Behdad Esfahbod 7d382fa276 [cmap] Implement collect_unicodes() for Format0/6/10 2018-08-25 09:42:52 -07:00
Behdad Esfahbod bd0e542525 [cmap] Simplify collect_unicodes()
Don't use accelerator (almost).  Hooks up Format13 as well.
2018-08-25 09:33:30 -07:00
Behdad Esfahbod d60c465627 Rename get_all_codepoints() to collect_unicodes() 2018-08-25 08:48:42 -07:00
Behdad Esfahbod 531051b8b9 [ot-font] Return char-not-found if mapped to gid 0
OpenType cmap table can use gid=0 to mean "not covered" to produce
more optimized cmap subtables.  Return false from get_nominal_glyph()
for those.  hb-ft already does this.
2018-08-25 08:44:18 -07:00
Garret Rieger 2bdd903c69 [subset] limit the max codepoint value to the unicode limit.
When collecting all codepoints in the cmap avoid using large amount of memory for fonts that declare coverage over all 32 bit integers.

Behdad Esfahbod 5b93f69169 Rename some X-terminated members to Z-terminated
X-terminated means don't access this, it's not located correctly.
Z-terminated means this is a C array with no bound checking.

Behdad Esfahbod d1f16fce96 Don't use %zu
Some of our bots / compilers don't like it. Wasn't caught by bots because this
is only in debug code.

Context needs to be called 'c'. The TRACE_* rely on that.

Behdad Esfahbod de2118ed7a Make sanitize() a const method
This makes a lot of code safer.  We only try modifying the object in one
place, after making sure it's safe to do so.  So, do a const_cast<> in
that one place...

Behdad Esfahbod 7627100f42 Mark unsigned integer literals with the u suffix

Behdad Esfahbod 7d4ada66c9 Mark unsed members with a "Z" suffix
There may be more.  There are members that are by definition
redundant or reserved and not needed, NOT what we *currently*
don't use.

I'm sure there's more...

Behdad Esfahbod 257d1adfa1 [ot-font] Work around broken cmap subtable format 4 length
Roboto was hitting this.  FreeType also has pretty much the
same code for this, in ttcmap.c:tt_cmap4_validate():

    /* in certain fonts, the `length' field is invalid and goes */
    /* out of bound.  We try to correct this here...            */
    if ( table + length > valid->limit )
    {
      if ( valid->level >= FT_VALIDATE_TIGHT )
        FT_INVALID_TOO_SHORT;

      length = (FT_UInt)( valid->limit - table );
