ruby on rails - Parsing string to add to URL-encoded URL

Question

Given the string:

"Hello there world"

how can I create a URL-encoded string like this:

"Hello%20there%20world"

I would also like to know what to do if the string has other symbols too, like:

"hello there: world, how are you"

What would is the easiest way to do so? I was going to parse and then build some code for that.

In 2019, URI.encode is obsolete and should not be used.

require 'uri'

URI.encode("Hello there world")
#=> "Hello%20there%20world"
URI.encode("hello there: world, how are you")
#=> "hello%20there:%20world,%20how%20are%20you"

URI.decode("Hello%20there%20world")
#=> "Hello there world"
