It was a minimal sample taken from from a larger project.

I have just discovered that the compilation error has nothing to do with
the hyphen.

Then I have the question about lpaths: do I have to remove all instances
of \letterpercent?

They seem to work fine, but I had the impression that \letterpercent was
mandatory and now I don’t know whether it is allowed or simply forbidden.
