Simplicity is better than complexity.

Surely base64-encoding the filenames would not be too much hardship? Personally, I would be inclined to do that anyway, because trying to use shell commands to manipulate a file called ¦¦¦¦¯¯Ì_.it will be painful.

I know this is a matter of taste, and merely trying to impose one person's tastes on everyone is not a reason to change the kernel. But on the other hand, the marginal extra disk space saving (ten bytes?) from being able to put arbitrary binary stuff in filenames without encoding does not outweigh the many good reasons that Wheeler gave for changing.
