If you don't know what codeset was used to encode a file, there isn't much that can be done to guess at what it might be.
It is easy to guess that it is just ASCII if there aren't any bytes with the high order bit set and there aren't any NUL bytes. It is easy to guess that it might be UTF-16 if every other byte is a NUL byte. Guessing that some text might be encoded in one of the EBCDIC codesets might not be too hard, but correctly guessing which variant is another matter. And, other than that, good luck. The differences between the various 8859-* character sets is only obvious to most people if you know what the text in the file is supposed to be beforehand.

MAKEDEV.LOCAL(8)					    BSD System Manager's Manual 					  MAKEDEV.LOCAL(8)

NAME
MAKEDEV.local -- create site-specific device special files SYNOPSIS
MAKEDEV.local [-fMsu] [-m mknod] [-p pax] [-t mtree] {all | site-specific-argument} [...] DESCRIPTION
MAKEDEV.local is used to create site-specific device special files. Each argument may be the word all or a site-specific argument. By default, there are no valid site-specific arguments, and the all argument has no effect; This may be changed by editing the script. The script is in /dev/MAKEDEV.local. Devices are created in the current working directory; in normal use, MAKEDEV.local should be invoked with /dev as the current working directory. Supported options for MAKEDEV.local are the same as for MAKEDEV(8). FILES
/dev special device files directory /dev/MAKEDEV script that invokes MAKEDEV.local with the all argument. /dev/MAKEDEV.local script described in this man page SEE ALSO
config(1), intro(4), MAKEDEV(8), mknod(8) HISTORY
The MAKEDEV.local command appeared in 4.2BSD. Handling of the same command line options as MAKEDEV(8), and the use of MAKEDEV(8) as a func- tion library, was added in NetBSD 5.0. NOTES
The relationship between MAKEDEV.local and MAKEDEV(8) is complex: o If MAKEDEV(8) is invoked with the all or local argument, then it will invoke MAKEDEV.local as a child process, with options similar to those that were originally passed to MAKEDEV(8), and with the all argument. o MAKEDEV.local uses shell functions defined in MAKEDEV(8). This is done by loading MAKEDEV(8) using the shell ``.'' command, with the MAKEDEV_AS_LIBRARY variable set (to inform MAKEDEV(8) that it should behave as a function library, not as an independent program).
