Having a bit of trouble with alt characters… everything works fine in the Fontlab OpenType features window using

feature aalt {
sub O by Oalt;
sub Oacute by Oacutealt;
sub Ograve by Ogravealt;
sub Ocircumflex by Ocircumflexalt;
sub Odieresis by Odieresisalt;
sub Otilde by Otildealt;
sub Oslash by Oslashalt;
sub o by oalt;
sub oacute by oacutealt;
sub ograve by ogravealt;
sub ocircumflex by ocircumflexalt;
sub odieresis by odieresisalt;
sub otilde by otildealt;
sub oslash by oslashalt;
} aalt;

But I noticed there’s no way to access ’aalt’ in Illustrator CS3… so I wanted to add salt, ss01 and maybe titl as well in the OT features for multi-application access.

I found this thread containing a suggestion:

Whenever you define any features in your font that produce 1:1 substitutions by some alternates (salt, ss01-ss20, swsh, hist, smcp, c2sc etc.), you should link these features to aalt in the following way:

feature aalt {

feature salt;

feature ss01;

feature ss02;

feature hist;

feature smcp;

feature c2sc;

} aalt;

But not sure how to implement and ’link’ these… does it go above or below the ’aalt’ feature code?

And does aalt on it’s own just not show up in some applications such as Illustrator?

Thanks
