Hey Fred,
Suppose i have a string “abcde fghi” it should gives true, and suppose
if i
have a string “abcd %$# fghi” it should return false.

Thanks

Depends entirely on what you mean by special character?

That’s still not very precise. Do you mean anything that’s not a
letter or a space? What about punctuation, numbers etc… ? You’re
probably just going to end up with one of the builtin character
classes like \w or custom ones like [a-z]

yes basically i don’t want my string should contain any ‘punctuation’ if
so
then it should return false.

Hi Abhishek,

Take a look on this article:

More specifically, the last example.

On that case I just consider words. You will need to adapt it to your
needs.

You can use http://www.rubular.com/ to test and find the regex you
need.
