Ah, right. I missed that. mawk does the same thing BTW.

I think we could do it using perl without escaping, but upstream doesn't
accept perl as a dependency.

'\' is not allowed unescaped in URI's though. But it is probably safer
to escape it as well.
I guess escaping is the way to go then. So how about this clever pattern
which escapes both characters:
local escaped=$(echo "$1" | sed -e 's/[&\\]/\\&/g')
