Special characters are characters that cannot be found on your keyboard. These can include symbols, special mathematical characters, and characters from other languages. You can insert special characters into your documents by using Character Map.
Open Character Map by clicking the Start button , clicking All Programs, clicking Accessories, clicking System Tools, and then clicking Character Map.
In the Font list, type or select the font you want to use.
Click the special character you want to insert into the document.
Click Select, and then click Copy.
Open your document and position the cursor where you want the special character to appear.
On the Edit menu, click Paste.
If you know the keystroke value of the special character you want to insert, you can insert the special character directly into your document by using your keyboard. To do so, open the document and position the cursor where you want the special character to appear. Then, with NUM LOCK on, press and hold the ALT key, and then press the keys on the numeric keypad that represent the keystroke value of the character you want to input.
After you finish typing, release the ALT key, and Windows generates the character you specified.
To find the keystroke value (ASCII code) for a special character, open Character Map, and then click the character you want to insert. If the character has a keystroke value, it will appear in the lower-right corner of the Character Map window.
