If you're on a Windows machine, here's how you can use the character map to add special characters (accented letters, etc) or symbols to the text in your images.

1. Click on the Windows Start menu, then select Programs > Accessories > System Tools > Character Map to open the Windows character map. Or click Start > Run, and type charmap.

2. Select the font that you want to use from the pulldown menu. You'll see a grid with all the characters available in that font.

3. Click on a character to see an enlarged view. To copy the character to your clipboard, click Select, and then click Copy. Or just double-click on the character. (See also the keyboard shortcut for the selected character in the lower right corner of the window. You can type it directly into Photoshop.)

4. To paste the character in your image, return to your graphics program and select the Type tool (make sure you're using the same font). Click on your image, where you want the character to appear. Then go to Edit > Paste, or just right-click and choose Paste. That's all!
