Builds an array of bits in <parameter>map</parameter> marking the

<parameter>*next</parameter> is set to contains the base code point
for the next page in <parameter>a</parameter>. Returns the base code
point for the page, or <constant>FC_CHARSET_DONE</constant> if
<parameter>a</parameter> contains no pages. As an example, if
<function>FcCharSetFirstPage</function> returns
<literal>0x300</literal> and fills <parameter>map</parameter> with
<literallayout class="monospaced">
0xffffffff 0xffffffff 0x01000008 0x44300002 0xffffd7f0 0xfffffffb 0xffff7fff 0xffff0003
</literallayout>
Then the page contains code points <literal>0x300</literal> through
<literal>0x33f</literal> (the first 64 code points on the page)
because <parameter>map[0]</parameter> and
<parameter>map[1]</parameter> both have all their bits set. It also
contains code points <literal>0x343</literal> (<parameter>0x300 + 32*2
+ (4-1)</parameter>) and <literal>0x35e</literal> (<parameter>0x300 +
32*2 + (31-1)</parameter>) because <parameter>map[2]</parameter> has
the 4th and 31st bits set. The code points represented by
<literal>map[3]</literal> and later are left as an excercise for the
reader ;).
