■ Escape sequences work for both String and char. Escape sequences appear in single quotes for a char, in double quotes for a String. i.e.
char c = ‘\b’;
String s = “\u00c1”;
■ The compiler doesn’t check inside a String escape sequence after the first 4 digits. i.e.
String s = “\u0000foobah”; works and ignores the foobah part
■ Here are the legal escape sequences:
\n new line feed
\f form feed
\r carriage return
\” double quote mark
\’ single quote mark
\xxx octal character in range 000-377. Higher than 377 won’t compile. Illegal digits like 8’s or 9's or A's won’t compile.
\uxxxx hex full 16-bit character
