Old style kerning
Is there a way to globally edit kerning pairs for old style numerals?
For example (though it's a recurrent, decade-long issue for me), the current book I'm typesetting has folios set in the typeface Winchester (roman old style figures). The native kerning of Winchester, as with lots of fonts, has too much space after the "1," and I'd like to modify Quark'x kerning table to correct this.
Is this possible?
