encodef

Unix/Linux/POSIX typically allow almost any byte in a filename, but this flexibility is the source of many problems and vulnerabilities.

This problem is described in "Fixing Unix/Linux/POSIX Filenames: Control Characters (such as Newline), Leading Dashes, and Other Problems" (http://www.dwheeler.com/essays/fixing-unix-linux-filenames.html). Ways of writing shell programs to work around this are discussed in "Filenames and Pathnames in Shell: How to do it correctly" (http://www.dwheeler.com/essays/filenames-in-shell.html). One approach, which does not have some of the problems of other approaches, is to use encodef... which is this package.
