I have three J’s in the letters J ,J.01 and J.02.
And, I have three ligatures IJ ,IJ.01 and IJ.02.
Therefore, I want to substitute…
I J → IJ
I J.01 → IJ.01
I J.02 → IJ.02
But I could only substitute to IJ.
sub I J by IJ; sub I J.01 by IJ.01; sub I J.02 by IJ.02;
sub J from [J.01 J.02]; sub IJ from [IJ.01 IJ.02];
What am I doing wrong?
