Discussion:
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.
Proposed resolution:
Change the entry for noconv in the table under paragraph 4 in section 30.4.2.5.3 [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).
