'unsafe' characters

[mnot@…]

In the rules for comparison of URIs [section 3.2.3], it says:

    Characters other than those in the "reserved" and "unsafe" 
    sets (see RFC 2396 [42]) are equivalent to their ""%" HEX HEX" encoding.

but RFC 2396 has no definition of a character set called "unsafe".

The paragraph should read:

    Characters other than those in the "reserved" set (see
    RFC 2396 [42]) are equivalent to their ""%" HEX HEX" encoding.

This was an historical artifact. An earlier HTTP draft had defined a set of 'unsafe' characters, but they were characters that were not valid in a URI, so making a special case in the comparison rule was not needed.
