That is true. UTF-8 wouldn't cause any more problems than ascii already does, such as some filesystems not allowing : and * in filenames among other characters.

Well at least that seems like they did something right when they extended FAT with VFAT. Doesn't make FAT a good filesystem, but it does make the filename extension pretty nice, much as it is an ugly hack too.

The constant rewriting of the same sectors that store the FAT is really bad for some types of flash and other removeably media (like DVD-RAM).
I hadn't noticed any big overhead in UDF, although packet writing may add some overhead itself (I never used packet writing).
