export LANG=de_DE.ISO8859-15

on a Mac (NS port), and a directory that contains a folder named "Tätää"(i.e. a German umlaut), viewing the directory with `dired' fails with an error message. The trace is below.

The bugs here are
1. `decode-coding-region' signals an error (it is not documented to do so) 2. with this locale, "ls -la" will not output utf-8-nfd, even though it seems that we expect this.

Debugger entered--Lisp error: (wrong-type-argument wholenump nil)
