<h2><a name="truetype-unicode">Deducing Unicode Ranges for TrueType</a></h2>
176+
177+
This information is available in
178+
the font by looking at the 'ulUnicodeRange' bits in the 'OS/2' table (if it has one),
179+
which holds a bitfield representation of the set. This table is
180+
defined in revision 1.66 of the TrueType specification, from
181+
Microsoft. Considering this information as a set, each element
182+
corresponds to a Unicode 1.1 character block, and the presence of that
183+
element in the set indicates that the font has one or more glyph
184+
representations to represent at least one character in that block. The
185+
set has 128 elements as described below. The order generally follows
186+
that in the Unicode 1.1 standard. This table may be used to convert
187+
the information in a TrueType font into a CSS 'unicode-range'
188+
descriptor.

<p class=comment>The TrueType bitfield system has the problem that it
288+
is tied to Unicode 1.1 and is unable to cope with Unicode expansion -
289+
it is unable to represent Tibetan for example.
