Answer 1

You can use the codePointAt(int index) method of java.lang.String for that. Here's an example:

"a".codePointAt(0) --> 97
"é".codePointAt(0) --> 233

If you want to avoid creating strings unnecessarily, the following works as well and can be used for char arrays:

Character.codePointAt(new char[] {'a'},0)
