需要特殊字符的密码中是否有我不应该支持的特殊字符？ （WebMatrix C＃）

Question

I have a password that requires special characters and was wondering if there were any special characters that I shouldn't support, such as "=" or "`" or ">", etc.

Here is what I have so far:

        if(c!='!' && c!='@' && c!='#' && c!='$' && c!='%' && c!='^' && c!='&' && c!='*' && c!='(' && c!=')' && c!='-' && c!='_' && c!='+' && c!='=' && c!='~')
        {
            Scount++;
            if(Scount >= password.Length)
            {
                errorMessage = "Your password must contain at least one special character.";
            }
        }

Ok, I guess I know I don't want to support angle brackets, but is there like a standard set of special characters that most sites support, or characters that I should definitely stay away from (besides angle brackets, those would probably trip up the WebMatrix validator in a lot of cases).

Please do not comment on the fact that I am not using a regular expression to check for patterns. I know this and I do not care. This was the first thing that worked for me, so that's what I'm going with.

Thanks for any help!

Ever since I saw this excellent cartoon on XKCD on password strength, any site that forces me to use upper or lower case chars, numeric or alphabetic... well it makes me mad. The only checking your site should do, should be checking for the length of the password.

If people want to enter 0bscur€ passwords fine, but don't force them to.
