How to check that string consists only from characters `A-z-—’', space and of length from 1 to 250 symbols?
I need a regex that checks that a string consists only from characters "A-z-—’'`", space and of length from 1 to 250 symbols.
I have a regex ^[A-z-—’'` ]{1,250}$ but it also finds strings like John[:
Why I allows strings with square brackets?
Solution
Please, note, that you should use a-zA-Z pattern for English letters, since current pattern A-z includes extra characters (consult ASCII table):
A, B, ..., Z, [, \, ], ^, _, `, a, b, ..., z
^ ^
extra characters to be included
So the correct pattern is
^[A-Za-z-—’'` ]{1,250}$
