   .. attribute:: BOT

      Flag indicating that special handling of the beginning
      of text paragraph can be applied to this buffer. Should usually
      be set, unless you are passing to the buffer only part
      of the text without the full context.







   .. attribute:: DEFAULT

      The default buffer flag.







   .. attribute:: DEFINED

      All currently defined flags: Since: 4.4.0







   .. attribute:: DO_NOT_INSERT_DOTTED_CIRCLE

      Flag indicating that a dotted circle should
      not be inserted in the rendering of incorrect
      character sequences (such at <0905 093E>). Since: 2.4.0







   .. attribute:: EOT

      Flag indicating that special handling of the end of text
      paragraph can be applied to this buffer, similar to
      ``HB_BUFFER_FLAG_BOT``.







   .. attribute:: PRESERVE_DEFAULT_IGNORABLES

      Flag indication that character with Default_Ignorable
      Unicode property should use the corresponding glyph
      from the font, instead of hiding them (done by
      replacing them with the space glyph and zeroing the
      advance width.)  This flag takes precedence over
      ``HB_BUFFER_FLAG_REMOVE_DEFAULT_IGNORABLES``.







   .. attribute:: PRODUCE_SAFE_TO_INSERT_TATWEEL

      Flag indicating that the ``HB_GLYPH_FLAG_SAFE_TO_INSERT_TATWEEL``
      glyph-flag should be produced by the shaper. By default
      it will not be produced. Since: 5.1.0







   .. attribute:: PRODUCE_UNSAFE_TO_CONCAT

      Flag indicating that the ``HB_GLYPH_FLAG_UNSAFE_TO_CONCAT``
      glyph-flag should be produced by the shaper. By default
      it will not be produced since it incurs a cost. Since: 4.0.0







   .. attribute:: REMOVE_DEFAULT_IGNORABLES

      Flag indication that character with Default_Ignorable
      Unicode property should be removed from glyph string
      instead of hiding them (done by replacing them with the
      space glyph and zeroing the advance width.)
      ``HB_BUFFER_FLAG_PRESERVE_DEFAULT_IGNORABLES`` takes
      precedence over this flag. Since: 1.8.0







   .. attribute:: VERIFY

      Flag indicating that the :func:`~gi.repository.HarfBuzz.shape` call and its variants
      should perform various verification processes on the results
      of the shaping operation on the buffer.  If the verification
      fails, then either a buffer message is sent, if a message
      handler is installed on the buffer, or a message is written
      to standard error.  In either case, the shaping result might
      be modified to show the failed output. Since: 3.4.0
