The issue is that your original URI is not a valid URI since it
contains characters which are not allowed in the URI.  Basically you
need to encode parameters _before_ you put them in the URI to make it
a valid URI and have URI.split work successfully:

irb(main):044:0> u = URI.parse 'http://foo.com/posts'
=> #<URI::HTTP:0x956a280 URL:http://foo.com/posts>
irb(main):045:0> u.query =
{id:30,limit:'יי'}.map{|k,v|"#{k}=#{URI.encode(v.to_s)}"}.join '&'
=> "id=30&limit=%C3%A9%C3%A9"
irb(main):046:0> u.fragment='time=1305298413'
=> "time=1305298413"
irb(main):047:0> u
=> #<URI::HTTP:0x956a280
URL:http://foo.com/posts?id=30&limit=%C3%A9%C3%A9#time=1305298413>
irb(main):048:0> puts u
http://foo.com/posts?id=30&limit=%C3%A9%C3%A9#time=1305298413
=> nil

Kind regards
