After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
This is "as designed". The Sylfaen font doesn''t contain the glyphs and the WYSIWYG control shows the fallback font which in this case is the SimSun font.
