“cloud” or "cloud" - is the quotation mark same? [duplicate]
I found two different quotation marks, "cloud" and “cloud”. What's the difference between these? Should I always use "" or “”.
The English straight double quotation mark "" was an invention of the typewriter era.
Because typewriters worked by mechanical devices at that time, the number of keys had to be minimized, so this type of quotation mark was invented as a last resort.
Technically, we don't use typewriters anymore, so there is no key-number restriction and avoid using such quotation marks in normal writing.
