The Arkandis Digital Foundry publishes a variety of comprehensive font families, apparently expressing high artistic merit, under an open license.
Support in LaTeX through external packages has been submitted into CTAN.
For example, the
venturisadf package has integrated the Venturis font family.
From the documentation for the CTAN package:
…condensed and standard-width Venturis regular and bold provide a choice of oldstyle and lining figures, upright and italic small capitals and alternate swash characters while the regular upright face also offers end-of-word swashes. All of these features are accessible in LaTeX through the included package files…
The same document shows examples of these features, including small capitals.
The CTAN index suggests, apparently incorrectly, that the package contains OTF representations of the fonts.
The greater discrepancy, however, is that the OTF representations available for general use directly from the foundry appear not to contain the
smcp feature, as revealed by inspection through
otfinfo -f. Indeed, when these files are used in XeLaTeX through the
fontspec package, the small capitals are not displayed in blocks formatted using
\scshape, and the engine warns about the appearance of the command.
The discrepancy is partly but inadequately resolved by a note, on the foundry’s site, seeming to indicate that most collections currently lack small-capital glyphs.
If the small-capital glyphs are seen in the LaTeX package, then the font collections must include them, and ideally general applications using OTF, including XeLaTeX, can use them.
From where are the small-capital glyphs being taken for the TeX font definitions? Can the glyphs also be used with the OTF files? If not, why?
