I have been convinced that soft hyphen is a control character and
not something visual, it should be used as a «break-indicator»
rather than as a hyphenation character, interpretation of which is
left as an excercise for the processing software.  I have no idea
still but would guess groff uses "hyphen minus" U+002D or hyphen
U+2010 if Unicode is possible.

Sorry.  Truly.
