find-coding-systems-region

find-coding-systems-region is a compiled Lisp function in `mule-cmds.el'.

(find-coding-systems-region FROM TO)

Return a list of proper coding systems to encode a text between FROM and TO.

If FROM is a string, find coding systems in that instead of the buffer.
All coding systems in the list can safely encode any multibyte characters
in the text.

If the text contains no multibyte characters, return a list of a single
element `undecided'.
