You can set font-backends that are supported but not active by default: (make-frame '((font-backend uniscribe))) but (frame-parameter nil 'font-backend) returns '(harfbuzz gdi) on Windows. --0000000000005884e40598b41687 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable

Is a good idea, but it doesn't r= eally work. You can set font-backends that
are supported but not active by default:
