For some reason ul(1) produces ESC ( B, which means switch
to US ASCII character set. These can be ignored, and less(1)
does ignore them.

It is what is written on the man page and what less does.  I should update it.

Maybe -R is a better idea.  Maybe it is what sbase used to have.

I see ^O (shift-in) characters at the end of bold sequences.  Is that what you 
mean?  Less does not handle these neither, but I can, I could just set it to 
ignore them.

This will be very convenient, I was not aware of such a diversity

Yes, I will change it after line folding.

Do not hesitate to ask for explanation if something is unclear in the source.

Silly me, I thought it was -R. I works, but if you place
util-linux's ul(1) between man(1) and iode you will see
a problem.

I'm working on libgraffiti which ul(1) will use, it will
support all escape sequences (I have read long lists of
escape sequences to find a pattern that recognise all
of them) along will things like combining marks. This
library will also be useful for pagers, terminals, and
similar programs.

iode seem to be able to do everything needed to view
man pages, but unlike ul(1) and most(1) it doesn't
support e.g. `printf 'aaa\r___'`, but it doesn't have
to as ul(1) can be used.

I would recommend making +R the default, what would
probably reduce confusion for users.

I made escape sequences tooglable with flags, maybe that is the reason.

You can try enabling colour interpreting with +R (or disabling it with -R).  
Either as command-line flag or as keybinding.

There is also +/-N for line number, and I am trying line wrapping / stripping 
with +/-S in a "folding" branch.

I will iddle in #suckless if that helps.
