> cpct    <unknown feature>
> dlig    Discretionary Ligatures
> fwid    Full Widths
> halt    Alternate Half Widths
> hwid    Half Widths
> nalt    Alternate Annotation Forms
> pwid    Proportional Widths
> trad    Traditional Forms
> vert    Vertical Writing
> vhal    Alternate Vertical Half Metrics
> vrt2    Vertical Alternates and Rotation)
