Overview of changes leading to 0.9.31
Wednesday, July 16, 2014
=====================================
- Only accept valid UTF-8/16/32; we missed many cases before.
- Better shaping of invalid UTF-8/16/32. Falls back to
U+FFFD REPLACEMENT CHARACTER now.
- With all changes in this release, the buffer will contain fully
valid Unicode after hb_buffer_add_utf8/16/32 no matter how
broken the input is. This can be overriden though. See below.
- Fix Mongolian Variation Selectors for fonts without GDEF.
- Fix minor invalid buffer access.
- Accept zh-Hant and zh-Hans language tags. hb_ot_tag_to_language()
now uses these instead of private tags.
- Build fixes.
- New API:
* hb_buffer_add_codepoints(). This does what hb_buffer_add_utf32()
used to do, ie. no validity check on the input at all. add_utf32
now replaces invalid Unicode codepoints with the replacement
character (see below).
* hb_buffer_set_replacement_codepoint()
* hb_buffer_get_replacement_codepoint()
Previously, in hb_buffer_add_utf8 and hb_buffer_add_utf16, when
we detected broken input, we replaced that with (hb_codepoint_t)-1.
This has changed to use U+FFFD now, but can be changed using these
new API.
