Drool.... One would assume the other ligatures, too.

The standard fonts only came with "fi" and "fl". Going beyond that would have only made sense for users who'd gone out and found fonts that had expert sets available.

An expert set, BTW, is just a supplementary font with the missing typography-geek glyphs from a standard one: "ffl"-ligature, fraction-composing glyphs, small caps, and so on. Major foundries sell them, but usually only on book fonts. All the extra glyphs you need have Unicode code points nowadays, except for small caps and superscript letters, which are viewed by Unicode as being the same glyphs as normal letters but in a different font.
