About Fonts and Character Encoding
The PDF specification requires that PDF readers support a core set of fonts. These fonts are as follows:
- Courier (Normal, Bold, Oblique, and BoldOblique variants)
- Helvetica (Normal, Bold, Oblique, and BoldOblique variants)
- Times (Normal, Bold, Oblique, and BoldOblique variants)
- Symbol
- ZapfDingbats
These fonts only support Windows ANSI encoding. In order for a PDF to
display characters that are not available in Windows ANSI you must
supply an external font, which will be embedded in the PDF. dompdf will
embed any referenced true-type font in the PDF that has been pre-loaded
or is referenced in a CSS @font-face rule.
Dompdf supports the same fonts as the underlying R&OS PDF class: Type 1 (.pfb) and TrueType (.ttf) so long as the font metrics (.afm/.ufm) are available. The bundled, PHP-based php-font-lib provides support for loading and sub-setting fonts.
As of dompdf 0.6.0 the DejaVu TrueType fonts
have been pre-installed to give dompdf decent Unicode character coverage
by default. To use the DejaVu fonts remember to reference the font in your
stylesheet, e.g. body { font-family: DejaVu Sans; } (for DejaVu Sans).
Here's an example on how to load a custom font.
use Dompdf\Dompdf;
require '../vendor/autoload.php';
$html = <<<HTML
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
