Inserting special characters
From Apache OpenOffice Wiki
A "special" character is one not found on the keyboard in front of the user. For example, © ¾ æ ç ñ ö ø ¢ are all special characters to those with US or UK keyboards. To insert a special character:
- Place the cursor where you want the character to appear.
- Click Insert > Special Character to open the Special Characters window (Figure 7).
- Select the characters you wish to insert, in order, then click OK. The selected characters are shown in the lower left of the dialog. As you select a character, it is shown on the lower right, along with its numerical code.
