For the allowed characters you can use
^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$
to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.
For the invalid characters you can use
[<>'"/;`%]
to check for them.
To combine both into a single regex you can use
^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])
but you'd need a regex engine that allows lookahead.
[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*
This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.
You haven't actually asked a question, but assuming you have one, this could be your answer...
Assuming all characters, except the "Special Characters" are allowed you can write
String regex = "^[^<>'\"/;`%]*$";
