Ah yes.  This one requires a fix in 2.0.12 I am afraid.  Basically if
you unread a byte from a byte array stream (and byte array streams were
the only straightforward way around some coding system problems), the
file position becomes total crap and that's what's used for the error
messages and for other processing like switching to the Scheme reader in
# or $ constructs.

So basically for 2.0.11 you would have to back out the patch using byte
streams and instead have to fuzz around with %default-port-encoding and
similar (which is _guaranteed_ to stop working in Guile 2.1 since the
Guile developers considered this last way I found for getting sensible
no-conversion behavior a bug).

That was more or less the last time when I decided "screw you, I am
waiting for the next Guile version if at all".
