Agreed. And this broad problem has bitten others
as well, including Kit Baum, Roger Newson
and myself. What we need is some way of inhibiting
Stata from interpreting the local macro, and
the only way to progress might be to read in the
file as binary. Nick Winter has some code which
you might want to look at.
Alternatively, it might be easier to do this
outside Stata: Awk, Perl, Python, whatever.
If there's some character you never use normally,
a combination approach might be to map ` to
that character, do most of the processing
in Stata, and then reverse the mapping.
