Answer 1

Those "UTF-8" codes are no such thing. They're actually just Unicode values, as per the Unicode code charts.

So an 'é' is actually U+00E9 - in UTF-8 it would be represented by two bytes { 0xc3, 0xa9 }.

Now to get the Unicode value - or to be more precise the UTF-16 value, as that's what Java uses internally - you just need to convert the value to an integer:

char c = '\u00e9'; // c is now e-acute
int i = c; // i is now 233
