[R12.2.4] What is the user password policy?

Hi, Gurus

I want confirm the user password policy for EBS R12.2.4.

I want confirm what is the valid character for EBS 12.2.4.

Due to below document, only UPPER characters, & numbers could be used ( "A"--"Z" and "0" --"9"), Am I right?

By the way, what is the max password length of the password?
