This is my current code

    response['Content-Type'] = 'application/octet-stream'
    response['Content-Disposition'] = 'attachment; filename="results.csv"'
    writer = UnicodeWriter(response, quoting=csv.QUOTE_ALL, encoding="utf-8")

I want to convert to utf -16 . BOm data is this but don't know how to insert it From here https://stackoverflow.com/a/4440143

echo "\xEF\xBB\xBF"; // UTF-8 BOM

But i want it for python and utf-16

I tried opening that csv in notepad and insert \xef\xbb\xb in beginning and excel displayed that correctly. But it is also visible before first column.

How can i hide that because user wont like that

这些行中的任何一行都为编码编写了正确的 BOM。如果 BOM 正确，Excel 不应显示它。

writer = UnicodeWriter(response, quoting=csv.QUOTE_ALL, encoding="utf-8-sig")

或者：

writer = UnicodeWriter(response, quoting=csv.QUOTE_ALL, encoding="utf16")

utf8,utf-16le并且utf-16be 不要写 BOM。

我认为您插入了错误的 BOM。从https://en.wikipedia.org/wiki/Byte_order_mark#UTF-16它建议您应该使用 FF FE 或 FE FF（取决于大端或小端）

python 文档（位于http://docs.python.org/2/howto/unicode.html）建议有 utf-16 的编码设置。此外，“这些编码还有一些变体，例如用于小端和大端编码的 'utf-16-le' 和 'utf-16-be'”。也许这些将允许在写入过程中自动插入 BOM。
