因為要申請憑證，但前面填寫欄位的資訊忘記
透過
openssl req -in 憑證名稱.csr -noout -text
欄位資訊會出現像是這樣 \C3\BBO\C3\A5_\C3\A5\C3\AB
這樣子我該如何去轉換成英文呢

你這不會是英文...這通常是用非ascii的字元給openssl去簽，但是沒有注意編碼。
而且有點怪怪的，像我用正常的憑證去看，欄位會是 \xE6\xB8而不是像你的 \C3\BB。

建議用windows的憑證檢視器看，這個能正確處理憑證的中文欄位。

是的，但想詢問的是 OU欄位資訊會顯示 \C3\BBO\C3\A5_\C3\A5\C3\AB 這種格式，想請問這是哪種編碼? 我該如何去轉換

我不知道如何轉換
只看得出不太像中文

找了一個中文OU的憑證有如下
