Documentation

Alist of filename patterns vs corresponding coding systems.

Each element looks like (REGEXP . CODING-SYSTEM). A file whose name matches REGEXP is decoded by CODING-SYSTEM on reading.

The settings in this alist take priority over coding: tags in the file (see the function set-auto-coding) and the contents of file-coding-system-alist.

This variable was added, or its default value changed, in Emacs 24.1.

Probably introduced at or before Emacs version 20.3.
