it seems that `.man` files are in troff(1) format, which uses backslash
escapes up the wazoo (however that is spelled).  it seems that (one way)
to getting a backslash character through troff is representing it as
"\e".

for my *particular* instance, where the backslash is in an org src
block, the below modification to `(org-man-src-block)` may work.

presumably one might have backslash sequences in example blocks, or in
the main text, or ...?  i don't know enough to have any idea if there is
some general mechanism that might solve all those.

cheers, Greg
