> Attached is a sample pdf with one of the droid fonts fully embedded in the above manner (free, Apache 2 license):
> http://android.git.kernel.org/?p=platform/frameworks/base.git;a=tree;f=data/fonts;hb=HEAD
> (The attached file has DroidSans instead of DroidSansFallback as in the log to keep the file size down, but it has the same result)
> (I was able to hack fix by changing PDType0 to extends PDTrueTypeFont, but that seems like a terrible hack).
