No Unicode doesn't. But yes, is *does* follow that decoding C0/C1 control codes produces a Unicode code point of equal value. RTFM. TUS 6.2, p. 544:
"There are 65 code points set aside in the Unicode Standard for compatibility with the C0 and C1 control codes defined in the ISO/IEC 2022 framework. ... The Unicode Standard provides for the intact interchange of these code points, neither adding to nor subtracting from their semantics. The semantics of the control codes are generally determined by the application with which they are used. However, in the absence of specific application uses, they may be interpreted according to the control function semantics specified in ISO/IEC 6429:1992." --Ken latin1 explicitly doesn't define characters (or control codes) in those ranges, but unicode does. It doesn't directly follow that decoding a byte in those undefined ranges produces a unicode-point of equal value.
