START and END are buffer positions specifying the region.
CODING-SYSTEM-LIST is a list of coding systems to check.
The value is an alist ((CODING-SYSTEM POS0 POS1 ...) ...), where
CODING-SYSTEM is a member of CODING-SYSTEM-LIST and can't encode the
whole region, POS0, POS1, ... are buffer positions where non-encodable
characters are found.
If all coding systems in CODING-SYSTEM-LIST can encode the region, the
value is nil.

If some of the coding systems cannot encode the whole region, value is
an alist, each element of which has the form (CODING-SYSTEM POS1 POS2 ...),
which means that CODING-SYSTEM cannot encode the text at buffer positions

START may be a string. In that case, check if the string is
encodable, and the value contains indices to the string instead of
buffer positions. END is ignored.
