This is a font for the Ancient alphabet from Stargate. It isn't entirely complete, but it should have enough characters to be useful in most GUIs running in English if you should decide to use it this way.
I didn't create this alphabet. I only created the font. The alphabet is not mine, but the font is, so please don't steal it. But feel free to use it in your deviations or whatever personal uses you'd like. If you intend to use it commercially, you could contact me, and you probably need to contact MGM and whoever else who might be involved with Stargate and would need to know. Otherwise, I don't really care.
Edit: This is an updated version that includes the newly discovered letter Z and two other letters which are assumed to be Q and X. Note that these two letters may be incorrect. This font also has all of the punctuation and extra symbols you'll probably need to run in English. Other languages may not be supported because of the lack of diacritics in Ancient.
Edit 2: It has been brought to my attention by sgeurika [link]
that the Ancient equivalent of K is more narrow than I had made it in my font. This mistake has been fixed. So, the font is no longer monospaced, if that makes a difference.
Edit 3: I've fixed the position of the Q and Z, which were previously reversed, as well as the size of the numbers. So, until we find out the new F or U (whichever it is that changes), this should be the final update that you've all been waiting for. Let me know if I missed anything.
Edit 4: Some people have experienced problems with the font file becoming corrupted when downloaded, so the .ttf file has been compressed and reuploaded as a .zip archive. Please comment to let me know whether this solved your problem or if it created new ones.
