Do I need to know all the unicode values? Please Advise.. This is for SCJP 1.4 exam prep..

Is there a chart that has the all values? Has there been any questions on knowing these values?

Thanks

Actually I got what I wanted @ http://www.unicode.org/Public/4.1.0/charts/CodeCharts.pdf

Unicode is just a code table that assigns integer numbers to characters. The ASCII table you are probably already familiar with maps nicely to unicode.

In short, you do not have to know unicode. Nonetheless, as a professional programmer you should know the following ASCII/Unicode mappings:

From these mappings you should be able to compute anything else you would want to know. Anything else just look up in a table.

There are only 95,221 unicode characters. I think we should all memorize them just for fun!

No, I dont think that is expected from us. However, you can memorize some of them....
1. Unicodes for alphabets both upper and lower case letters. It would be enough if you know vaulue of "A", "a", "Z" and "z"
2. Unicodes for numbers 0 to 9.
3. Some escape sequences. Like /t=tabs, /n, /b etc.
