[text.encoding.cmp]

friend constexpr bool operator=(const text_encoding& a, const text_encoding& b) noexcept;

Returns: If a.mib_ == id::other && b.mib_ == id::other is true, then comp-name(a.name_,
b.name_).

Otherwise, a.mib_ == b.mib_.

friend constexpr bool operator=(const text_encoding& encoding, id i) noexcept;

Remarks: This operator induces an equivalence relation on its arguments if and only if i != id::other is true.
