# From http://en.wikipedia.org/wiki/Percent-encoding:
# The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values.
# Also sometimes JavaScript encode() function (deprecated) is being used; this uses %uXXXX encoding for UTF-8 chars
def self.utf_decode(str)
pct_decode(str) # decode %XX bits
.force_encoding('UTF-8') # Make sure the string is interpreting UTF-8 chars
.tap{|uri| validate_string_encoding(uri)}
.gsub(/%u([0-9a-z]{4})/) {|s| [$1.to_i(16)].pack("U")} # Decode %uXXXX encoded chars (JavaScript.encode())
.tap{|uri| validate_string_encoding(uri)}
end
# Use it by default
def self.decode(str)
