Isn't the code you use for a given OS handled by the OS itself? For instance, if in Windows I press Alt+0189 (in the numbers keys) I get the half-sign; but I know the in the Mac OS, if I enter 189 (no Alt or its equivalent or 0; nice one, Apple Computing!) I'd get capital omega (the symbol for ohm); but the Unicode code point is U+00BD, as shown by the (Windows) Character Map. The font though (Eurocrat) is a fairly old Type 1 PS font. (The Unicode code point matches the Windows code, but that is only coincidental.) A Mac character map, if there is such a thing, would only show the Unicode code point, because the 'Mac US Roman encoding' has no entry for 'vulgar fraction half', but the sign still exists in the font.

The same situation exists with the fi and fl ligatures, but reversed: they would be shown only as FB01 & FB02 in Windows, but also as 222 & 223 in a Mac OS.

It seems improbable that a font designer should have to provide encoding for Macs and Windows, although fonts, both PS and TrueType, are normally supplied, as separate files, for the Mac and Windows. And how he would manage to design an OT font, which would presumably need three different encodings, I cannot even imagine.

Not always. Remember that the Type 1 fonts were released in what, 1985? There was no sense of Unicode then; the practice of extending from ASCII's seven bits to eight bits was still fairly new, and each manufacturer went its own way. Fonts were expected to be encoded suitably; that's how the symbol stuff came about, and foreign language fonts.

What you describe is how most modern apps deal with type, but not what they did in those early days.

Yes, I realize that: I was trying, though, to make some sense of Type 1 PS fonts (presumably introduced by Adobe) and the early TrueType fonts, which were introduced by Apple Computing (I'm being pedantic, because Apple Corps still exists) and taken up with enthusiasm by Microsoft. According to a Web page by Adobe, 'most' Type 1 PS fonts have either Adobe or Windows encoding, which was interpreted appropriately by ATM; this would explain the uniformity of the character sets pre-Unicode (and after). Unfortunately, it doesn't help Mac or Windows users at all if they can't get at the parts of the set outside what their application allows them to get at. Which brings us back to QuarkXPress 6.5 . . .

Nothing will bring me back to QuarkXPress.

If you want to play pedant, you need to get the name right: Apple Computer.

I just had to be drinking coffee right as I read that. Almost had to clean the screen!
