Hello,

when trying to create an executable script using `program-file', I realized=
 it
silently corrupts expressions with non-ascii characters.  Minimal reproduct=
ion I
did put together is:

    scheme@(guix-user)> ,use (guix)
    scheme@(guix-user)> ,build (program-file "foo" '(=CE=BB))
    $1 =3D "/gnu/store/im07w0ilskfycpkwid3n7s80hdv263cn-foo"
    scheme@(guix-user)> (call-with-input-file $1 read)
    ;;; <stdin>:3:22: warning: possibly unbound variable `$1'
    $2 =3D (?)

Notice that $2 is (?) instead of the expected (=CE=BB).  If there is a tech=
nical
reason why this cannot be handled correctly, it would be great if it at lea=
st
failed with an error instead of a silent corruption.

Have a nice day,
Tomas Volf

There are only two hard things in Computer Science:
cache invalidation, naming things and off-by-one errors.
