@small_snow or @bunbuku

Would you actually use this sentence to say "Please open the window"?
We often see this kind of translation for "Please ....", but it's always felt a little strange to me.



どうぞ窓を開けてください。

Would one or both of these match better?

You may go ahead and open the window if you want to.

>it's always felt a little strange to me.

I agree with you. It might be used in some situation, but I think it's an unusual expression. The latter sentence you've showed us could be okay for that Japanese translation.
@small_snow What do you think about that?

>どうぞ窓を開けてください。

現在はどうか分かりませんが、「ひと昔前の中学英語の模範訳」のように思います。正直なところ、日常生活でそのフレーズは使ったことも聞いたこともないです。

>Would one or both of these match better?
あえて付けるなら、bunbukuさん同様、後者の #9192484 かな。

少し話はずれますが、私が興味深いと思ったのは、先日AlanF_USさんが削除された
#38468 You will please open the window.
と同じような表現：
You will please leave the room.（どうぞ部屋から出てください）

が、ひと昔前の辞書には記載されていますが、比較的最近の辞書には見当たらないことです（私が見落としているだけかもしれませんが）時代と共に言葉が変わるように教え方も変わるのであれば、この文はなくてもいいように思います。
個人的な意見です。

※じゃぁ、古文はどうするの？と言う疑問は残りますが。それはそれ。これはこれ。ということで。

> 少し話はずれますが、私が興味深いと思ったのは、先日AlanF_USさんが削除された
#38468 You will please open the window.

To me, if I heard the above sentence that AlanF_US deleted, I would take it to be an imperative sentence. I would personally never say it.

Without looking at the phrase in context, this doesn't prove it's acceptable or used to be acceptable usage, but here is Google Books Ngram viewer.

We do have some good sentences starting with どうぞ and ending with してください。
Notice that these are "offers" not "requests."

While I'm not fussed whether this sentence remains or not, after all, there are hundreds of sentences containing terms like どうぞ and 窓, I see there are about 50 sentences of the どうぞ...てください pattern, and virtually all have "please" in them. None contain "if you want to". It's the pattern I was taught back in the last century to request something politely.
