So since thie is on a Java site I'm going to guess you want the Octal codes for the UNICODE character set right? :-)
Ashamed to expose how old I am but the old DOS days use an ASCII set with a Key Page variable for locale settings.
So on my Windows system I can hold down the ALT key and use the numeric key pad to enter in a letter directly.
?is what you want right? I type ALT-130
This URL will show you the other values. Jump to 130
