X-Symbol on Carbon Emacs 1.6.0: problem with sub/superscripts

[Makarius]

Carbon Emacs 1.6.0, X-Symbol (with either version of the ttf fonts), Courier Fontset. Now sub/superscripts of letters are displayed in greek instead of lattin! For example see A\<^sub>W where the W comes out as capital Omega; the same for lower case.

It does work correctly with the default "16-dot medium" fontset of Carbon Emacs. So maybe Carbon Emacs is to blame, but there might be a workaround for PG.

[Makarius]

After looking a bit more closely it seems that PG can actually do something here. There are already strange workaroungs like x-symbol-latin-force-use and the problem only occurs for Courier size 18 and 24, which are somehow special to PG.

Does this happen with both ttf fonts installed or just one?

See lib/pg-fontsets.el for how to define some fontsets uniformly, in case that helps.

I'm marking as "wontfix" because X-Symbol is dead after the next release, and running on Carbon Emacs was never a fully supported configuration. If someone finds a patch, please upload to this ticket nonetheless.
