Open</a> specification all the way to <a
 href="http://standards.iso.org/ittf/PubliclyAvailableStandards/c052136_ISO_IEC_14496-22_2009%28E%29.zip">ISO/IEC
14496-22:2009(E)</a>, the OpenType Coverage table, format 2, contains
this descriptive text:<br>
<br>
<blockquote type="cite">The Coverage Indexes for the first range begin
with zero (0), and the Start Coverage Indexes for each<br>
succeeding range are determined by adding the length of the preceding
range (End GlyphID - Start GlyphID +<br>
1) to the array Index.<br>
</blockquote>
<br>
This whole sentence seems nonsensical (at least to me) given that the
Start Coverage Index for each range is actually specified in the Range
Record itself:<br>

So what am I missing? What is the descriptive text in the spec trying
to say?<br>
<br>
Thanks,<br>
