What are the valid identifiers in the following?
Select all valid answers or none.
a. char a = 'a';
b. char \u0061 = 'a';
c. ch\u0061r a = 'a';
All are correct!!! Surprised at b & c are correct?

The reason being that Unicode gets translated during the reading of a line, so the compiler sees a translated String.
This is the reason you can't use the Unicode representation for carriage-return and new-line in Strings - they get translated into a line end when the compiler reads the source.
