They were already added (in the std namespace) in C++20 (see
[cuchar.syn] <http://eel.is/c++draft/cuchar.syn> and [c.mb.wcs]
<http://eel.is/c++draft/c.mb.wcs> p7-11).

Yes, that is expected. We will need to adjust the wording for the linked
sections above when we rebase:

[cuchar.syn]p1 <http://eel.is/c++draft/cuchar.syn#1>:

    The contents and meaning of the header <cuchar> are the same as the
    C standard library header <uchar.h>, except that it declares the
    additional mbrtoc8 and c8rtomb functions and does not declare types
    _char8_t, _char16_t_,_ nor char32_t.

[c.mb.wcs] <http://eel.is/c++draft/c.mb.wcs>:

    Align the specification for these functions with the other functions
    in that section to give them the "These functions have the semantics
    specified in the C standard library" treatment with appropriate "See
    also: ISO/IEC 9899:..." notes.
