;;; On Linux x86_64

I realized that DIRECTORY won't work with non-ascii filenames
unless I set PATHNAME-ENCODING-NAME (to :utf-8 in my case).
This is odd because DIRECTORY worked before without it.

Then, I found that RENAME-FILE does not work with non-ascii filenames
and discovered that CCL::UNIX-RENAME uses plain WITH-CSTRS. This is
even odder because I think I remember RENAME-FILE worked with Japanese
filenames before.

Here's my attempt to fix CCL::UNIX-RENAME for Linux. I left darwin and
windows version intact but they also wouldn't work for non-latin chars
as is? And nobody noticed it before? Or am I missing something?
