It's app/toolkit specific. E.g. with xterm you can enable it with -fa
and related options.

It's mainly about Xft. Most users of that also use fontconfig for
selecting the fonts to use, but that's not required.
Most apps/toolkits have used the modern text rendering infrastructure by
default for a long time, but a lot of terminal emulators are still
holding out for some reason.
