• How to make dot match newline characters using regular expressions 6 answers

How can i match text that is 10 characters at minimum and 4000 at maximum and that text can be any character. Furthermore i need to accept space tab carriage return and new lines.

I tried:

"/.{10,4000}$/"

But that didn't work! I think that the dot does not include carriage return for example.

So can anybody help me with this ?

Sorry any misspelling, i am Portuguese.
