Discetionary ligatures in display font
0

Hi all

I am designing a display typeface in Fontlab. It has substitute ligatures for pretty much every letter combination (like A_A, A_B, A_C...etc). I want to put them all as discretionary ligatures. The code at the moment looks like this:

feature dlig {
sub A A by A_A;
sub A B by A_B;
sub A C by A_C;
sub A D by A_D;
sub A E by A_E;
sub A F by A_F;
sub A G by A_G;
sub A H by A_H;
sub A I by A_I;
sub A J by A_J;
sub A K by A_K;
sub A L by A_L;
sub A M by A_M;
sub A N by A_N;
sub A O by A_O;
sub A P by A_P;
sub A R by A_R;
sub A S by A_S;
sub A T E by A_T_I;
sub A T I by A_T_E;
sub A T by A_T;
sub A U by A_U;
sub A V by A_V;
sub A W by A_W;
sub A X by A_X;
sub A Y by A_Y;
sub A Z by A_Z;

.......(and will eventually go all the way to Z_Z)....

} dlig;

I am afraid it may end up being huge and perhaps make the font slow, although it is a display font so most probably it won't be used for huge chunks of text.

Is there any other way to do it? I am not good at scripting and I've searched around but I couldn't find if there is another way to use classes to do it.

Any help will be greatly appreciated.

Thanks!

You're right, you can't use classes in this instance. The way you're going is the only way, so far as I can see.

Hi George

thank you very much for your reply.
I'll stick to that then.
