In the definitions of codecvt<>::do_out and do_in, they are specified to return noconv if "no conversion is needed". This definition is too vague, and does not say normatively what is done with the buffers.
Change the entry for noconv in the table under paragraph 4 in section 126.96.36.199.3 [locale.codecvt.virtuals] to read:
noconv: internT and externT are the same type, and input sequence is identical to converted sequence.
Change the Note in paragraph 2 to normative text as follows:
If returns noconv, internT and externT are the same type and the converted sequence is identical to the input sequence [from,from_next). to_next is set equal to to, the value of state is unchanged, and there are no changes to the values in [to, to_limit).
