翻译人员显然不知道什么代码将操作翻译的文本，因此他们必须知道如何输入所需的单引号／撇号。
The translator obviously does not know what code will manipulate the translated text, so they must know how to enter required single quotes or apostrophes.
当然，这三种操作符(单引号、双引号和反撇号)都有合法的用途，但是与英语中的例外一样，记住和掌握这些细微差异很令人头疼。
Certainly, all three operators-the single, double, and back quotation marks-serve a valid purpose, but like exceptions in English, memorizing and mastering the variations can be maddening.
单引号或双引号都可以包围字符串，这就允许引文中再包含引号或撇号。
Either single or double quotation marks can enclose strings, which permits quotes that contain quote marks or apostrophes.
