This is not a black and white, thing, you can't say that _any_ tool that falls is broken.

The fact that the Linux kernel can ignore the content of the file name does not mean that nothing have to. Managing char sets is not only a display problem, and it is not certainly Microsoft fault that someone invented a broken standard like ASCII from start. There are historical reasons why some protocols (and no just file sharing protocols, think of http/html) have standardized on some char set, and no matter what you say, any network protocol have to deal with that, cause machines used to speak in different ways. And you can't force everybody to have the same encoding. Actually the fact that the kernel accept everything worsen the problem, as it allows mixed char set file names to exists. But this is a different problem. Now if we could standardize everything on utf8 we would have no problem, and this is why, at least internally, we should standardize on it, and not propagate the plague of mixed incompatible char sets. We can and we should standardize at least at the user space level. People expect consistency from a distribution and the tools it ships.
