get char value in java

How can I get the UTF8 code of a char in Java ?
I have the char 'a' and I want the value 97
I have the char 'é' and I want the value 233

here is a table for more values

I tried

Character.getNumericValue(a)
but for a it gives me 10 and not 97, any idea why?

This seems very basic but any help would be appreciated!

Answer

char is actually a numeric type containing the unicode value (UTF-16, to be exact - you need two chars to represent characters outside the BMP) of the character. You can do everything with it that you can do with an int.

Character.getNumericValue() tries to interpret the character as a digit.
