What is the easiest/best/most correct way to iterate through the characters of a string in Java?
...hod is a constant time operation.

//Process char
}

What is a “surrogate pair” in Java?
...In the Unicode character encoding, characters are mapped to values between 0x0 and 0x10FFFF.
Internally, Java uses the UTF-16 encoding scheme to store strings of Unicode text. In UTF-16, 16-bit (two-byte) code units are used. Since 16 bits can only contain the range of characters from 0x0 to 0xFFFF...
