Overriding global XSS filtering

[eluser]besson3c[/eluser]
Hello,

I just realized that the global XSS filtering setting can mess up password inputs if the password includes certain characters. Is there a way to override this setting for particular form elements? If not, would it be possible to toggle this setting off temporarily while assigning this form input to a variable?

I could play around with this for myself, but I'm not sure what sorts of input will result in modification post-sanitization/filtering. Can anyone please provide me with an example?
