[Groff] Characters in grohtml

[Robert Marks]

(I have looked for a discussion of this topic in the archive, but in 
vain.)

I have recently moved to groff from troff DWB 2.0, and am looking 
forward to generating HTML code from
groff documents.  I was surprised to find (using grohtml version 1.15) 
that symbols such as \(^o and \(em and \(rq are not translated into 
their HTML equivalents of ô and — and ” respectively.

Is there a way to do this?  Something I'm missing?
