re: Post titles

An interesting phenomenon. I attempted to use an obscure post title, 4F01, but the system won't allow the capital letter.

It's not a particularly problematic issue, as it doesn't damage the reference. But ... well, why?

Does 4F01 correspond to some markup, code, or command? I figure there is a logical reason, as opposed to a random bug that nobody has ever noticed before. But, still, it just seems strange.

Unicode hex 4f01: 企 (Chinese, "enterprise")
