Unicode Hexadecimal Input Mode

To switch to Unicode hexadecimal code input method input mode, either press Compose u h, or select Unicode Hex from the input mode selection window. To switch to the octal number system, press Compose u o or select Unicode Octal. For information on accessing the input mode selection window, see Figure 5–1.

To use these input modes, you need to know either the hexadecimal or the octal code point values of the characters. Refer to The Unicode Standard, Version 3.0 for the mapping between code point values and characters.

If you are in the Unicode hexadecimal code input mode, to input a character you would type four hexadecimal digits. Some sample hexadecimal values are:

• 00A1 for Inverted Exclamation Mark

• 03B2 for Greek Small Letter Beta

• AC00 for a Korean Hangul Syllable

• 30A1 for Japanese Katakana Letter A

• 4E58 for a Unified Han character

You can use both uppercase and lowercase letters of A, B, C, D, E, and, F for hexadecimal digits. If you prefer the octal number system instead of hexadecimal numbers, you can input octal digits, 0 to 7. If you mistype a digit or two, you can delete the digits by using the Delete or Backspace key.
