<div style=""><font color="#242729" face="Arial, Helvetica Neue, Helvetica, sans-serif"><span style="font-size: 15px;">My thought is:</span></font></div>
<div style=""><font color="#242729" face="Arial, Helvetica Neue, Helvetica, sans-serif"><span style="font-size: 15px;">first get each position of each character from pango/cairo, then if no api to render one by one, I can use freetype library to render each
glyph, does it work?</span></font></div>
