Looks for text enclosed between two identical quotes
|
|||
|
|
(the probable quotechar) which are preceded and followed
|
|||
|
|
by the same character (the probable delimiter).
|
|||
|
|
For example:
|
|||
|
|
,'some text',
|
|||
|
|
The quote with the most wins, same with the delimiter.
|
|||
|
|
If there is no quotechar the delimiter can't be determined
|
|||
|
|
this way.
