----------------------------------------
I have the following code. In a nutshell i am slicing a string to pull out strings to use as keys in a hash. However when running the following code, I am getting odd results.

~~~ruby
context = "Marriott International World���s Most ADMIRED Lodging Company by FORTUNE for 14th yr. via @FortuneMagazine http://cnnmon.ie/1kcFZSQ"
slice_url = context.slice(105,24)
str = "http://cnnmon.ie/1kcFZSQ"
slice_url == str
redirects = {"http://cnnmon.ie/1kcFZSQ"=>"http://money.cnn.com/2014/02/06/leadership/marriott-hotels.pr.fortune"}
redirects.key?(slice_url)
redirects.key?(str)
~~~

The `slice_url` and `str` are equal, however when I look for the key in redirects with `slice_url` I get a `nil`, but when setting the string variable manually, I get a match and value.  I am not sure if this is an issue with the value returned by the string slice method or an issue with the hash.
