This font is based on - but differs slightly from - the Aurebesh lettering created by West End Games. My focus has been to accurately populate this font with letters that are seen in the movies of the original trilogy. After close examination of screenshots and officially available information, many letters have been revised or replaced.
Letters that do not appear in the trilogy were replaced. These include: Grek, Jenth, Osk, and Resh. (If you don't know what any of these letter names mean, don't worry about it; this info is for the Aurebesh purists.) Grek has been replaced with a modified version of Enth. Osk has been replaced with Orenth. Resh has been replaced by Nen. Jenth has been replaced with an entirely new letter, which I refer to as Jul. All other letters have been severely modified for accuracy. Arabic numerals (1,2,3, etc) have been used in the font, since Arabic numerals were used in the original trilogy. See the attached galbasic_table.gif for a full table of Galactic Basic letters and their respective keys.
NOTE: This font is simply a personal interpretation. It will not allow you to translate anything seen in the movies. I apologize if your favorite letters have been changed or removed.
