Im not aware of any injection attacks directly. In the past I have been able to force information disclosure via 500 error pages (file structure, other applications used, etc) by submitting sequences of characters like those you showed.

Subject: Extended ASCII characters used for injection

Hi list,

I have a web app and I want to block special characters in URL on the
web server. Do you know if there is a risk of injection (XSS...) with
extended ASCII char (%7f-%ff)?
Is there any reason to block these characters?

Thanks
Regards,
Nib
