Review Comment:
Thanks @symious for catching is problem and submitting this fix. As the uri
is included in the string2sign and signature validation do we need to extend
this encoding to support other special characters that need to be in ASCII hex
or vice-versa?
For the URLEncoder class, all alphanumeric characters remain the same after
encoding. However the spaces are converted to '+' that we correct for in line
251. All special characters ".", "-", "\*" , and remain the"_" same. With
all others converted to hex. Are there any other cases o f special characters
that we need to convert to hex similar to the '*"?
