It may be worth mentioning (or pointing to) the information regarding the 
interaction between special font and the .*char commands, particularly the 
fact that any "fallback" definitions with .schar will prevent groff finding 
the glyph in the fonts defined as "special" in the DESC file. (This prevents 
groff from finding the real glyph for users who have installed a more 
comprehensive symbol font (such as SymbolA, which contains all the glyphs we 
mark as fallbacks) and update their DESC file to replace "S" with "SymbolA". 
Currently the only way to avoid the uglier fallback is to include .special 
SymbolA in every document, but this would make it non-portable on systems 
which do not have SymbolA installed.

It is a shame .schars operate before "the already mounted (DESC) special 
fonts".

Cheers
