[XeTeX] Accessing ligatures from FontForge

[Andy Lin]

tex-text.map only provides for some punctuation marks. You can add
these lines to your tex-text.map file (or use it as a base and name it
something different, like tex-text-f.map). Semicolons are comment
characters. Below, only fi and fl ligatures are active.

You'll need to run the file through teckitcompile.exe to generate the
.tec that XeTeX uses.

;U+0066 U+0066	<>	U+FB00	; ff -> ff ligature
U+0066 U+0069	<>	U+FB01	; fi -> fi ligature
U+0066 U+006C	<>	U+FB02	; fl -> fl ligature
;U+0066 U+0066 U+0069	<>	U+FB03	; ffi -> ffi ligature
;U+0066 U+0066 U+006C	<>	U+FB04	; ffl -> ffl ligature
