html - helvetica font not working in wkhtmltopdf

Question

I have been trying to use Helvetica font while creating the pdf but the font is not reflected back in pdf.

I did some google and found some solutions but none are workable.

Tried Solution 1

I found similar thing here : Font issue

Tried the last solution mentioned over there

workaround is to define @font-face in your css and have src link to external host that is accessible by wkhtmltopdf

But the solution is not working.

Tried Solution 2 I also tried to use google font api, but result is still not workable. helvetica font

here is an example Example of custom font

Tried Solution 3 I tried doing it using css property @page. But that also is not working.

What is the approach for a workable solution.

Answer 1

The easiest way to fix wkhtmltopdf's font problems is to Base64 encode the font (you can use this tool) and include it in your CSS:

@font-face {
    font-family: 'Helvetica';
    src: url(data:font/truetype;charset=utf-8;base64,AAEAAAATAQA...
}

This works with all fonts (including Google Fonts), and guarantees cross-platform compatibility across different machines and operating systems.
