special characters handling

[Sandeep Manchikanti]

I want to all the special characters except space and single quote, how can i define a pattern for it.

i tried this - pattern="[]a-zA-Z0-9\!\[`\$\%\/\^\_\+\=\#\@\?\;\,\|\*\{\}\(\)\~\.\>\<\&\"\-]+"

gave input as ~!@`$%#^&*()

showed in web ~\!@`$%\#^\&*\(\)

now escape characters also got accepted - but \ char getting added

i want to store string as it is as how user entered

Let me know if there is a solution or any work around to handle it.

Thankyou
