/** Decodes a URL-encoded string.
In a Uniform Resource Identifier (URI), all non-ASCII bytes and several others (e.g., '<', '%', ' ')
are URL-encoded using 3 bytes by "%XY" where XY is the hexadecimal value of the byte. This function
decodes the URI restoring its original UTF-8 encoded content. Decoding is done in-place.
