Proposed resolution:

This wording is relative to N4618.

  1. Insert the following series of paragraphs to [any.bad_any_cast] as indicated:

    const char* what() const noexcept override;
    

    -?- Returns: An implementation-defined NTBS.

    -?- Remarks: The message may be a null-terminated multibyte string ([multibyte.strings]), suitable for conversion and display as a wstring ([string.classes], [locale.codecvt]).

Proposed change:

Add a paragraphs:

Returns: An implementation-defined NTBS.

Remarks: The message may be a null-terminated multibyte string (17.5.2.1.4.2), suitable for conversion and display as a wstring (21.3, 22.4.1.4).
