I have created an OpenType font in FontLab Studio 5 which has OpenType Features which include a full set of alternative uppercase glyphs, and a set of alternative numerals (ss1); I also set alternative numerals for fractions (frac)and - after a bit of testing and scratching my head and more testing - the OpenType frac code worked fine.
However, when I tried to write the code for the alternative Superscript and Subscript characters (incl numerals 0-9) which I need, I realised that I didn't know how to write it or whether to put it in the superscript .sups and subscript .subs OpenType code or whether to put it in the ss1 code... I'm not very good when it comes to writing code.
Does anyone know how I should write this code, and where to put it (ie in the sups/subs OpenType feature or in the ss1 alternative glyph set feature)?
Hope this makes sense and that someone can help me with this cos I am truly stumped.
