Type 1 versus OpenType font behaviorHi Ken,

It is virtually impossible that XEP itself displaces individual
characters vertically - it puts them as a string of text, not
as single glyphs. I'd rather suspect the problem is in the font.
Most probably, your PostScript font uses old-style digits.
(My paper copy of Webster has pages numbered with these;
perhaps you can find a similar example in some other
dictionary or encyclopaedia). Try to format the following
FO piece with your font:
<fo:inline text-decoration="underline">01234567890</fo:inline>
If I guessed right, than you should see the following:
- 0, 1, and 2 are small in size (like a small character - x-height tall);
- 6 and 8 are bigger, and rise above the x-height;
- 3, 4, 5, 7, and 9 are the same size as 6 and 8 but descend below the
baseline.
If so, you probably have to ask your font supplier for another
copy of the font. Strictly speaking, such a situation is not normal:
old-style digits should have different names in PostScript
('oneoldstyle', 'twooldstyle', etc. compared to 'one', 'two'
etc. for regular digits). You may ask the foundry why did
they code old-style glyphs with regular-style names.
Naturally, mine is only a guess. If I missed the point,
please send your font files with a problematic FO
sample to support@renderx.com, so that we can investigate
the problem further.
Best regards,
Nikolai Grigoriev
