letter-spacing is too large with wkhtmltopdf

Question

I\'m using wkhtmltopdf to download a webpage as pdf.

But the css property letter-spacing seems doesn\'t work

font-size:20px; letter-spacing:0px;
<         


        

Answer 1

letter-spacing is broken in wkhtmltopdf.
But i found other ways around for kerning:

1. You may set position for every letter. Kerning is used for headings so there are not so much letters usually.

2. You may alter the font file and set the custom kerning you want. Usually it would be enough to alter latin letters. I've tested this and it worked well. Used FontForge (http://fontforge.github.io/) for this. But may be there is a more convenient software.
