I don't know if there's an easy way to do that.

The easiest way is to put a comment on the first two lines containing:

-*- coding:iso-8859-1 -*-

Alternatively, you could put a comment in the last 512 bytes of the file 

Local Variables:
codingl iso-8859-1

Otherwise, you may use the file extension, or the file location  (or
really any regexp on the file path) to determine the encoding,
customizing the file-coding-system-alist variable.

(push '("^/some/dir/latin-1-files/.*" iso-8859-1 . iso-8859-1)

(push '("\\.iso-8859-1$" iso-8859-1 . iso-8859-1)
