iComment   Specifies the MSODOCEXCOMMENT value,
msodocexcommentEndTextRun.
The DocExComment_UnicodeForNextTextOut structure functions similarly to the
DocExComment_BeginTextRun and DocExComment_EndTextRun structures. However,
DocExComment_UnicodeForNextTextOut specifies Unicode code points for only the
following EMF TextOut record, rather than for a block of EMF content bounded by begin
and end structures.
C++
The members of the DocExComment_UnicodeForNextTextOut structure are as follows:
ident   Specifies the constant value, msodocexsignature, which identifies this EMF
comment as containing semantic information.
iComment   Specifies the MSODOCEXCOMMENT value,
msodocexcommentUnicodeForNextTextOut.
cGlyphIndex   Specifies the size of an array that follows this structure. This array
implements a glyph index table that maps Unicode code points in the actual text
to the corresponding glyphs in the EMF. Each element of the array corresponds to
a code point in the text. The value of that element specifies the first glyph used to
render that code point in the EMF. Two or more adjacent code points may have the
same value in the array, which means that they both resolve to the same glyph.
cwchActualText   Specifies the size of the sequence of Unicode code points that
follow the glyph index table. This is the text that a consumer of the document can
use for searching, copying/pasting, and accessibility.
The DocExComment_EPSColor structure specifies color information for an encapsulated
PostScript (EPS) file embedded in the EMF. For more information about this structure,

    DWORD ident {};
