第一に格納されている外部(おそらくマルチバイト)表現に文字を変換するために吹き込まれたロケールのstd::basic_streambuf::overflowを使用して、関連した文字列(ファイルに)出力領域からデータを書き込むことを除いて、基本クラスcodecvt::out()のように振る舞う一時バッファ(必要に応じて大きさの割り当て)は、I / Oは、ファイルにすべて完全に変換されたバイトをコピーするファイルを使用しています.
Original:
Behaves like the base class std::basic_streambuf::overflow, except that to write the data from the put area to the associated character sequence (to the file), first uses codecvt::out() of the imbued locale to convert the characters into external (possibly multibyte) representation, stored in a temporary buffer (allocated as large as necessary), then uses file I/O to copy all fully-converted bytes into the file.

変換がstd::codecvt_base::errorで失敗した場合は、任意の出力を試みることなくTraits::eof()を返し.
Original:
If the conversion fails with std::codecvt_base::error, returns Traits::eof() without attempting any output.
