Inserting Special Characters
You can insert special characters into your worksheet by using one of the following two resources:
• The Ribbon—Select the desired symbol from the Math tab, Operators and Symbols group, Symbols list.
You cannot use this method to insert characters into a text region.
• The Windows Character Map—Lists all UNICODE values between hexadecimal 0x0020 and 0xFFFD. Click a character to display its UNICODE number and name. For some characters, the map displays a keystroke that you can use to insert the character into your worksheet.
