Non-Latin Characters lead to finder distress.

One of the nicest features of Macintosh from the time I first played on an SE30 is the capacity to quickly type non-Latin characters. While to many this might not seem like a big deal, for me being able to write Tetris™ without a second thought is a great convenience.

So I was very surprised when I began typing µ in the Finder under Snow Leopard and didn't end up on a file that started with µ but rather on m. As if that wasn't irritating enough µ is not treated as m so the file becomes completely unreachable by alphabetic selection. This is something I use almost constantly in Finder so having a file unreachable is even worse than merely having the character interpreted incorrectly.

Just to be certain that this wasn't merely a flaw with that one character I examined other common characters.
ƒ, é, π, ∑ all suffer from the same problem, misinterpreted when typed and interpreted correctly during the comparison.

So the question is, “Is this an error in how I set up my machine, an error in the string comparison system, or an error in the Finder program?”
