$Id: encguess,v 0.4 2023/11/10 01:10:50 dankogai Exp $

# SYNOPSIS

      encguess [switches] filename...

## SWITCHES

-h
  show this message and exit.
-s
  specify a list of "suspect encoding types" to test, separated by either ":" or ","
-S
  output a list of all acceptable encoding types that can be used with the -s param
-u
  suppress display of unidentified types

## EXAMPLES:

- Guess encoding of a file named "test.txt", using only the default suspect types.

         encguess test.txt

- Guess the encoding type of a file named "test.txt", using the suspect types "euc-jp,shiftjis,7bit-jis".

         encguess -s euc-jp,shiftjis,7bit-jis test.txt
         encguess -s euc-jp:shiftjis:7bit-jis test.txt

- Guess the encoding type of several files, do not display results for unidentified files.

         encguess -us euc-jp,shiftjis,7bit-jis test*.txt

# DESCRIPTION

The encoding identification is done by checking one encoding type at a time until all but the right type are eliminated. The set of encoding types to try is defined by the -s parameter and defaults to ascii, utf8 and UTF-16/32 with BOM. This can be overridden by passing one or more encoding types via the -s parameter. If you need to pass in multiple suspect encoding types, use a quoted string with the a space separating each value.
