AFAIK, "letter spacing" is not a font property; that is, the font designer specifies character widths and any character-pair kerning.
I figured applications which allow you to adjust letterspacing are repositioning each character rather than placing per the widths and kerns. So, in the PDF, I expected to see each character absolutely positioned. However, looking at PDF from my old (v9) Corel Draw, it look like something else is going on; I'm not sure what. 1.0 0.0 0.0 1.0 0.0 0.0 cm 0.12 0.1 0.09 rg BT 92.0072 692.4002 TD /F12 24.0 Tf -0.0082 Tw (This is a test of 24pt ) Tj 220.1162 0.0 TD (Arial) Tj 0.12 0.1 0.09 rg -220.1159 -53.6241 TD 3.3384 Tc 3.3256 Tw (Letter) Tj 78.0426 0.0 TD ( spacing) Tj 115.7253 0.0 TD ( 125%) Tj -193.7679 -53.6241 TD (L.S.)
