By default buffer for PDF files are in unibyte mode.  I use
doc-view-mode and store some custom data in some directory below it's
cache directory, which I want to remove, when the buffer gets killed.
The removing of this directory (e.g. .doc-view/FILENAME-83432/data/) is
done with delete-directory, but fails, if FILENAME contains multibyte
character (see below).  So I am actually not inserting anything into a
buffer.

Debugger entered--Lisp error: (file-error "Removing old name" "no such file or 
directory"
