Character class with negated "]"

How do I indicated a character class with a negated "]"?

I want to negate: * [ ]
The problems is then that attempts like
    [^*[]]+
will not work, as the "]" will be interpreted as the character class
closing bracket. Therefore, I use things like
    ([^*[-^]|"\\"|"^")+
relying on ASCII ranges.

But I thought it ought to exist something simpler (and more readable).
