Logon.exe and special characters

Logon.exe is a great program. I have a problem where I am trying to enter a % sign as a password. The application does not seem to recognize it. Is there anyway to input special characters. I tried ascii code and it did not work. Any help will be greatly appreciated.

I use that utility alot and the best way i've found to use it with "%" is as follows. Hope it helps.

//Unlock the desktop
dim vUser, string "-u user"
dim vPassword, string
dim vUnlock, string

//use a double% to represent a single in the final string

ConcatEx( "-p ", "%%", "Q6q*2WCh9^p", vPassword )
ConcatEx( "C:\\Program Files\\24x7 Automation 3\\utilities\\logon.exe ", vUser, vPassword, vUnlock )

RunandWait( vUnlock, "C:\\Program Files\\24x7 Automation 3\\utilities\\", 0, vProcess )
