This may be a dumb question, but why rename them at all? If all the lowercase characters are small caps, does it make any difference what they're named?

Nick, clever idea! Keep the glyph names as they are, only assign unicode values to "a.small", "b.small" etc. instead of "a", "b" etc.

Hmm, Wouldnt that also take some time? Sort of the same amount of time it takes to do this little manual process.

Since I dont know the unicode numbers in my head I have to look them up first, and then enter them manually to the small caps slots.

Or is there an easier way?

It would take some time, but only once ;) You could copy and edit one of FontLab’s naming files (.nam) in /Library/Application Support/FontLab/Mapping so that includes the small cap names instead of the lowercase names:

%%FONTLAB NAMETABLE: Small Caps
0x0020 space
0x0021 exclam
0x0022 quotedbl
[...]
0x0041 A
0x0042 B
0x0043 C
[...]
0x0061 a.small
0x0062 b.small
0x0063 c.small
0x0064 d.small
0x0065 e.small
[...]

... and then use this file via the menu Glyph -> Glyph Names -> Generate Unicode to reassign the unicode values in the current font.

By the way, good luck for Letters From Sweden :)

Ah, I see. Smart.

Thanks for that, and thanks for wishing us good luck. If it doesnt work, I can always start submitting fonts to Google instead :)

...I could of course also become a psychologist, surely it must work the other way around too.
