open-uri and illegal url characters

[bsagert]

Hello, n00b here. I use open-uri to read a Yahoo .csv file of stock
and index quotes. Yahoo indices start with a circumflex ("^") which a
browser will convert to "%5e". The following line is rejected by Yahoo
(andRuby) ==>s=open('http://download.finance.yahoo.com
/d/quotes.csv?s=^DJI,^SPX,^IXIC&f=sl1d1t1nohgv&e=.csv').read
Is there a Ruby method that will automatically convert illegal
characters into url-speak? Thanks, Bill

Oops, that url is ==> http://download.finance.yahoo.com/d/quotes.csv?s=^DJI,^SPX,^IXIC&f=sl1d1t1nohgv&e=.csv

require 'cgi'

CGI.escape('^') => "%5E"

Jeez, I really am a newbie. Of course the above link will work fine in
a browser.
The point is, it won't work in a Ruby script! The open-uri module
won't convert "^"
to "%5e" and the question is, is there a Ruby way?
