Good to see increased awareness of font embedding issues and the serious need to use fonts which explicitely allow it when you want to do it.

Fontforge offers an Embeddable dropdown and tick boxes in its font information panel to view the fsType - and modify it if you have the rights to branch the font - as well as an os2_fstype object accessible via python.

You always need to make sure to check the embeddability rights associated with the font you want to use. Of course when the designer has chosen a licensing model which explicitly allows embedding like the OFL then no need to worry.

But people wishing to use open fonts under the GPL need to do due diligence of checking what happens there... What with the experimental font exception and its problems...
