<h5 id="C1_Util_DX_DirectWrite_FontFace_GetGlyphIndices_System_Int32____remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>Note that this mapping is primarily provided for line layout engines built on top of the physical font API. Because of OpenType glyph substitution and line layout character substitution, the nominal conversion does not always correspond to how a Unicode string will map to glyph indices when rendering using a particular font face. Also, note that Unicode variant selectors provide for alternate mappings for character to glyph. This call will always return the default variant.</p>
