I vaguely remember that there are some discussions concerning soft
hyphen being nonprinting or not. Might have been on
<URL:http://www.cs.tut.fi/~jkorpela/shy.html>. I don't have a clear
opinion here at the moment. It is a printing character in fonts like
MinionPro or Charis SIL.

Typically a flatter version of accents acute and grave are used for
uppercase letters. This is a purely presentational thing that indeed
should be left to the font.
