ENH: Should we implement an escape character?

[seberg]

Extending the tokenizer for it should not be super hard. The advantage would be that without escape character, we do not have full csv support.

Basically:

• It is not really difficult or time consuming to add
• It might be a good new feature as an additional incentive that we also improve loadtxt.

[seberg]

Just to note, the idea is that it would be nice to grow full support for csv.Dialect (as in full support except the line terminator ☺, which python also doesn't support): https://docs.python.org/3/library/csv.html#dialects-and-formatting-parameters

Pandas has support for this, and it seems like a nice thing.

Possible followup.
