Special characters

How to enter the characters

Copy the character from the left column.

Another option is to enter the character by character code using the Alt key. This works from some Microsoft Windows applications.

For Alt + Code:
1. Check that Num Lock is activated.
2. Press and hold the Alt key while entering the 4-digit code on the numerical keypad, for example 0181. The code is converted to the special character, for example µ.
For Code Alt+x:
1. Type the 4-character code, for example 2030.
2. Press and hold the Alt key while pressing x. The code is converted to the special character, for example ‰.
