Right now, I have two fonts with old-style numbers.
One, Linux Libertine, a true-type font.
Two, PFL Neu, a type 1 font based on URW Palladio.
These both have old-style figures in the same file, and I have seen
with Font Forge that the glyphs are labeled the same: zero.oldstyle,
one.oldstyle... etc.
However, I cannot use the old-style figures from the type1 font.
It prints a warning saying that the OpenType feature 'Numbers=OldStyle'
is not available.
Why can't XeTeX find the o.s. numbers? Is it a limitation of type 1
fonts?
If I put the old-style glyphs in a different file, and load the font
with the SmallCapsFont=<file> option, then it still prints the warning
about old-style numbers not available, but you can actually get o.s.
figures selecting small-caps, e.g. \textsc{12345}. Whereas \textup{123}
uses normal figures. It's not ideal, but it works. The problem is that
it's inconsistent, because the true-type font is insensitive to
\textsc \textup as long as o.s. figures are concerned, it only obeys
the OpenType feature "Numbers" option.
Any comment appreciated :)
Cheers.
