Meaning
little_endian
入力はリトルエンディアンのバイト順序(のみ、デフォルトはビッグエンディアンのUTF-16の入力に適用されます)であると仮定します
Original:
assume the input is in little-endian byte order (applies to UTF-16 input only, the default is big-endian)

consume_header
入力シーケンスの開始時に存在して、(UTF-16の場合)の場合、バイトオーダーマークを消費し、復号化するため、それが指定するバイトオーダー入力の残りの部分に依存しています
Original:
consume the byte order mark, if present at the start of input sequence, and (in case of UTF-16), rely on the byte order it specifies for decoding the rest of the input

BOM(Byte Order Mark)で始まるファイルを読み込むときstd::consume_headerが選択されていない場合は、Unicode文字U + FEFF(ZERO WIDTH改行なしスペース)は、文字列の内容の最初の文字のように読むことができます.
Original:
If std::consume_header is not selected when reading a file beginning with byte order mark, the Unicode character U+FEFF (Zero width non-breaking space) will be read as the first character of the string content.

#include <locale>
#include <codecvt>
int main()
{
    // UTF-8 data with BOM
    std::ofstream("text.txt") << u8"\ufeffz\u6c34\U0001d10b";
    // read the UTF8 file, skipping the BOM
    std::wifstream fin("text.txt");
    fin.imbue(std::locale(fin.getloc(),
                          new std::codecvt_utf8<wchar_t, 0x10ffff, std::consume_header>));
    for(wchar_t c; fin.get(c); )
        std::cout << std::hex << std::showbase << c << '\n';
}

Output:

0x7a
0x6c34
