XPP is able to access any glyph in an OTF font that is bound to a Unicode value.
However important character sets that may be included in a font such as Old Style Figures, Small caps or (tabular/lining/proportional) figures that do not have a corresponding Unicode value in a font cannot be access by XPP.
It would be very useful to be able to selectively utilize all the glyphs that are included in OTF fonts.
- Having the ability to tell XPP to automatically switch to tabular alignment figures if I'm a non-sub/superscripted figure in a table.
- Switch to Old Style Figures if a certain pagination style table is in effect.
