Hi, http://2d.laboratorium.net/post/108351875900/small-caps-big-problem complains about small caps from Word, etc., compared with small caps designed by the designer. Thought it might be of interest given troff's long-time S\s-2MALL\s0 C\s-2APS\s0, especially used in the formatting of Unix. IIRC, Dennis Ritchie said they did it because the CAT gave them the possibility, but it was regretted for the UNIX/Unix confusion it caused.
Heirloom troff, http://heirloom.sourceforge.net/doctools.html, says Mechanisms for typesetting small capitals, old-style numerals, and arbitrary ligatures e.g. using Type 1 “expert” or OpenType fonts are provided. Don't know what the other various troff's support for proper small caps is, e.g. plucking them from the OpenType font? Cheers, Ralph.
