クォーテーションマークについて
- Comments欄にも書いてあるが、プログラミングにおけるクォーテーションマークは以下を使っている。
- シングルクォーテーションマーク:U+0027 (apostrophe)
- ダブルクォーテーションマーク:U+0022 (quotation mark)
- つまり
- シングルクォート = apostrophe
- ダブルクォート = quotation mark
メモ
- 洋書のセリフ部分は、‘...’ のように、U+2018 (left single quotation mark) と U+2019 (right single quotation mark) で囲まれていることがある。所有を表す部分のアポストロフィにまで、U+2019 (right single quotation mark) が使われるようだ(紛らわしいと思うがなぜ?)。
