Right! Oof, forgot them. So OK: altogether we have
space, tab, hyphen, and the assigned discretionary hyphen
character -- four characters that will perform a
"discretionary wrap", so to speak. But none of them is both
invisible and zero width. The Tab comes closest;
conceivably with a soft font you could use a Substitution
table, set width=0, and set TS=0, but then you won't have
access to [259] and [260], and the whole thing gets more and
more complicated. If I were in Patricia's shoes, I'd use a
proportional font, and just use the space character, which
would be quite thin -- I think it looks better anyway (an
unpadded em dash crowding directly up against another
character looks godawful).

For the following, are you using the built-in separator
table, or are you writing and loading your own SE: table to
include these characters? I've tried it both ways, and:

03 -- Doesn't work for me
13 -- *Forces* (!) a wrap. Anyway, a paragraph (not word) separator
126 -- Your discretionary hyphen char??
155 -- Doesn't work here
169 -- Nope
181 -- "
182 -- "
198 -- "
199 -- "
200+ -- Don't work here
