4.1.2. Unsafe characters

In canonical form, certain characters such as spaces, control characters, some characters whose ASCII code is used differently in different national character variant 7 bit sets, and all 8bit characters beyond DEL (7F hex) of the ISO Latin-1 set, shall not be used unencoded. This is a recommendation for trouble-free interchange, and as indicated below, the encoded set may be extended or reduced.
