Designers often use symbols, such as the copyright or registered trademark characters, within promotional art. The GNU Image Manipulation Program, or GIMP, facilitates this by allowing you to add symbols directly into the GIMP Text Editor instead of selecting them from a menu. To do this, you must enter the character's Unicode number. These numbers are cross-platform codes that describe every supported character, including foreign letters, geometric shapes and commonly used symbols.
Select the Text Tool in the Toolbox and click on the canvas to open the GIMP Text Editor.
Press "Ctrl," "Shift" and "U" together on the keyboard.
Type the Unicode number of the character you wish to insert, then press "Enter."
Press "Close" on the GIMP Text Editor to view your text when you are finished.
