FYI:
-
There are so-called typographic quotation marks: These are the quotes you are using/seeing in most formatted text. Opening and closing marks are different, and these quotes are language-specific. For example in English
“word”, German„word“or»word«, French« word », etc.
Similar in its single form:‘word’,‚word‘or›word‹,‹ word ›, etc. -
Then you have the so-called typewriter quotation marks, also called straight quotes: These are the quotes you have to use in any kind of code. Opening and closing marks are the same, and they are not language-specific:
"word"and in its single form'word'.
