We have data that has ; as separator and hasĀ fields that look like this:
abcd \; efgh
That's a single field.
The backslash escapes the ; so that the data is abcd ; efgh.
This same data set also has
abcd \n efgh
Here the backslash precedes an ordinary non-delimiter. The data is supposed to be abcd \n efgh. That is, this data set requires the backslash to be retained in the data when it is not preceding the start of a delimiter.
Am I missing something or is it impossible to model this?
