Regex patter to allow space : I have one regex which allows one Upper case, one Lower case, 8-16 characters and Most special characters and space. I want add allow space in the regex. 

My regex is as follow :

    (?=^.{8,16}$)(?=.*[\!\"\#\$\%\&\'\(\)\*\+\,\-\.\/\:\;\<\>\=\?\@\[\]\{\}\\\\\^\_\`\~\|])(?=.*[a-z])(?=.*[A-Z])(?!.*\s)[0-9a-zA-Z\!\"\#\$\%\&\'\(\)\*\+\,\-\.\/\:\;\<\>\=\?\@\[\]\{\}\\\\\^\_\`\~\|]]*$


I just want to add space in this. I have tried **\s** and **[ ]?** but nothing works. 

I have checked the regex on https://regex101.com/

Any suggestions would be appreciated.
