I’m a bit late, but thanks for fixing it!

What often works in such cases is to force ISO-8859-1 encoding
(“Latin-1”), which is a “catch-all” encoding (it’s an 8-bit encoding
that covers the 256 values):

  (with-fluids ((%default-port-encoding "ISO-8859-1"))
    (substitute* file-in-arbitrary-ascii-compatible-encoding
      …))
