--- Comment #14 from Sam Morris sam@robots.org.uk 2011-09-22 07:19:50 CDT --- Well spootted. The other font files seem to have the version string both in single-byte and multibyte encodings. I edited only the single-byte encoded version of DroidSans-Bold.ttf and found that Wine picked up the changes, but Windows did not. So Wine should probably always use the double-byte encoded strings.
I don't know enough to be able to remove one or other of the version strings, so I don't know what Windows does when only a single-byte encoded version string is present.
