<h5 id="C1_Util_DX_DirectWrite_TextAnalysisSource_GetNumberSubstitution_System_Int32_System_Int32___remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>Any implementation should return the number substitution with an incremented reference count, and the analysis will release when finished with it (either before the next call or before it returns). However, the sink callback may hold onto it after that.</p>
