Will the tolerance (and support) grow for such quotation character alterna=

Do you care to achieve a safe data format description also for this use ca=

double quotation marks (\"\").\n";

Can such a message trigger any more thoughts and development ideas?

* Please avoid a typo in this message.

* Which formula do you propose for the length calculation?
