Unicode table

Computers support a vast number of characters beyond those visible on standard keyboards. To enhance your text—especially when working with mathematics, physics, or foreign languages—you can access these special characters and symbols using their code. The current code system is Unicode version 16.0, which specifies 155,063 characters. The different fonts associate a glyph to the codes. The codes are standardized so, e.g. dismal code 65, equal to 0x41 in hexadecimal is a Latin “A” in all fonts. The early code standard was the ascii (American Standard Code for Information Interchange) and defined only 128 (7 bit) characters with 95 coding for printable glyphs. It covers the Latin lower and upper case and the Arabic numerals (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9). The other 33 charterers in the ascii table are Unicode control characters. The extended ascii adds one bit to get to 255 characters to cover more language specific characters and symbols. The Unicode allow for 4 hexadecimal digits or 64 bit codes. With this many languages and special symbols can be coded.

To can access all characters and symbols from the keyboard you need to use key combinations.

Linux Systems:

On Linux, you can input special characters using their Unicode code points with the following key combination:

1. Press and hold Ctrl + Shift.

2. While holding these keys, press u.

3. Release all keys, then type the hexadecimal code of the desired character.

4. Press Enter or Spacebar to insert the character.

For example, to insert the character 'Ω' (which has the Unicode hex code 0x3a9):

• Press Ctrl + Shift + u.

• Release the keys, then type 3a9.

• Press Enter or Spacebar, and 'Ω' will appear.

Windows Systems:

Windows allows the insertion of special Unicode characters using Alt + x:

1. Type the hex Unicode for the symbol you want.

2. Press Alt + x and the character will appear.

For instance, to insert the character 'μ' (which has the Unicode hex code 0x3bc):

• Type 3bc.

• Press Alt + x and 'μ' will be inserted.
