  26       OpenType provides shaping models for the following scripts:

  28 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
  29 <li class="listitem"><p>
  30           The <span class="emphasis"><em>default</em></span> shaping model handles all
  31           non-complex scripts, and may also be used as a fallback for
  32           handling unrecognized scripts.
  33         </p></li>
  34 <li class="listitem">
  35 <p>
  36           The <span class="emphasis"><em>Indic</em></span> shaping model handles the Indic
  37           scripts Bengali, Devanagari, Gujarati, Gurmukhi, Kannada,
  38           Malayalam, Oriya, Tamil, Telugu, and Sinhala.
  39         </p>
  40 <p>
  41           The Indic shaping model was revised significantly in
  42           2005. To denote the change, a new set of <span class="emphasis"><em>script
  43           tags</em></span> was assigned for Bengali, Devanagari,
  44           Gujarati, Gurmukhi, Kannada, Malayalam, Oriya, Tamil, and
  45           Telugu. For the sake of clarity, the term "Indic2" is
  46           sometimes used to refer to the current, revised shaping
  47           model.

  88           Text runs that do not fall under one of the above shaping

  90           particular note is <span class="emphasis"><em>Emoji</em></span> shaping, which
  91           may involve variation-selector sequences and glyph
  92           substitution. Emoji shaping is handled by the default
