	    <para>

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

first page of Unicode coverage of <parameter>a</parameter>.

<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 ;).
