rfc2047-charset-to-coding-system

rfc2047-charset-to-coding-system is a compiled Lisp function in `rfc2047.el'.

(rfc2047-charset-to-coding-system CHARSET &optional ALLOW-OVERRIDE)

Return coding-system corresponding to MIME CHARSET.
If your Emacs implementation can't decode CHARSET, return nil.

If allow-override is given, use `mm-charset-override-alist' to
map undesired charset names to their replacement. This should
only be used for decoding, not for encoding.
