Description Peter Occil 2013-03-04 20:41:29 UTC 
In this part of the x-www-urlencoded parser:
------
If the use "_charset_" flag is set, name is "_charset_", and get an encoding for value does not return value, unset the use "_charset_" flag and set encoding override to the result of getting an encoding for value.
------
I assume you mean: "and get an encoding for value does not return failure".

Since otherwise the _charset_ parameter would be ignored if the encoding exactly equals a supported encoding in the Encoding Standard.

Also, the specification does not define what happens when a code point higher than U+00FF occurs in the input to the percent-decoding algorithm.  It seems to me that the code point is truncated to a byte, though that might not be the intention.
