 Dot Reph is best implemented in font using Opentype Glyph Class ‘Mark’. Base glyphs and conjuncts are not marked as ‘Mark’ class, but an Anchor point to those glyphs could be added indicating the position where Dot Reph would be placed.\\
 Harfbuzz and Uniscribe reorders Dot Reph after the base glyph/conjunct. For instance \texttt{hb-shape} utility (from Harfbuzz source tree) shows the output of {\meera ൎത്തു} \texttt{<dotreph, th1, xx(virama), th1, u1(u-sign)>} as \\  \texttt{[th1th1u1=0+2461|dotreph=0\@-575,-5+0]}. Thus, it is only necessary to add an Anchor point to glyph \texttt{th1th1u1} at the desired coordinate to render dotreph.\\
