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.
