Thank you. I am already using the first of these constructions (i.e. 
"control space", in the terminology of the TeXbook), as I thought I
made clear. The problem is that not only does it not work, it seems
that some of the following material gets gobbled up and lost.

I am also aware of the workarounds suggested, and I can use one or
more of them in running text. The problem also arises in math mode,
where "\ " is used to force a space. Most of the workarounds do not
work here, though I can achieve what I want, for example by defining
\spc to mean \mkern6mu and using that instead.

The fact is that "\ " doesn't behave in LaTeX2html as it does in
LaTeX. I believe that this is a bug. The fact that there are
workarounds doesn't alter this.
