The reason gridftp is picky is that URLs can only have US-ASCII
characters in them, and it doesn't want to do the encoding for you
because, I assume, that would be a fair amount of work. See RFC 1738,
1808, and 2396 for details if you are interested in tackling this
yourself. One approach may be to simply wrap the guc command with an
encoder.
