 <p>Many CJK characters have variant forms. They are a sort of grey area somewhere between being totally irrelevant and semantically distinct; for this reason, the Unicode consortium decided to introduce Ideographic Variation Sequences (IVS), consisting of a Unicode base character and one of 240 variant selectors (U+E0100-U+E01EF), instead of further extending the already huge code range for CJK characters.</p>
 <p>An IVS is registered and unique; for further details please refer to Unicode Technical Standard #37, the Ideographic Variation Database:</p>
 <p><a href="http://www.unicode.org/reports/tr37/">http://www.unicode.org/reports/tr37/</a></p>
 <p>To date (November 2014), the character with the most variants is U+9089, having 32 such IVS.</p>
 <p>Adobe and MS decided to support IVS with a new cmap subtable (format&nbsp;14). It is an odd subtable because it is not a mapping of input code points to glyphs, but contains lists of all variants supported by the font.</p>
 <p>A variant may be either &lsquo;default&rsquo; or &lsquo;non-default&rsquo;. A default variant is the one you will get for that code point if you look it up in the standard Unicode cmap. A non-default variant is a different glyph.</p>

 <h4>note</h4>
 <p>If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file. This is done to ensure that value&nbsp;0 always corresponds to the &lsquo;missing glyph&rsquo;.</p>
 <p>This function is only meaningful if a) the font has a variation selector cmap sub table, and b) the current charmap has a Unicode encoding.</p>

	<h4>note</h4>
	<p>If you use FreeType to manipulate the contents of font files directly, be aware that the glyph index returned by this function doesn't always correspond to the internal indices used within the file. This is done to ensure that value 0 always corresponds to the ‘missing glyph’.</p>
	<p>This function is only meaningful if a) the font has a variation selector cmap sub table, and b) the current charmap has a Unicode encoding.</p>
