To insert a Unicode character, type the character code, press ALT, and then press X. For example, to type a dollar symbol ($), type 0024, press ALT, and then press X. For more Unicode character codes, see Unicode character code charts by script.
If the character string literal has a prefix of N, the literal is treated as a Unicode string. When the N prefix is used, the characters in the literal are read as WCHAR characters. Any string literal with non-ASCII characters is treated as a Unicode literal by default.
u'\xe9' is a Unicode string that contains the unicode character U+00E9 (LATIN SMALL LETTER E WITH ACUTE).
Insert a character at the beginning of the String using the + operator. Insert a character at the end of the String using the + operator.
How to put a supplementary Unicode character (say, codepoint 10400) in a string literal? I have tried putting a surrogate pair like this:
String text = "TEST \uD801\uDC00"; System.out.println(text); but it doesn't seem to work.
UPDATE:
The good news is, the string is constructed properly.
Byte array in UTF-8: 54 45 53 54 20 f0 90 90 80
Byte array in UTF-16: fe ff 0 54 0 45 0 53 0 54 0 20 d8 1 dc 0
But the bad news is, it is not printed properly (in my Fedora box) and I can see a square instead of the expected symbol (my console didn't support unicode properly).
