CcsidGuesser

A utility for guessing the CCSID of files (based on file contents).

It can also fix CCSID tags and/or convert files to UTF-8!

Usage

Usage: java -jar ccsidguesser.jar  [options] <file>

    Valid options include:
        --show=top/topN/all: how many CCSID guesses to show (default is 'top1'), which shows the
                             top 1 result. A value of 'top' shows the top guess and some number
                             of very-near guesses.
        --format=<format>:   output format (default is 'ccsid'). See valid formats below.
        --convert=<mode>:    convert file to UTF-8 (default is 'none'). See valid modes below.
        --autofix            automatically and unapologetically change the CCSID tag of the file
                             to match the top guess for the file's contents (IBM i only)

    Valid formats include:
        ccsid:        Show the CCSID only
        enc:          Show the CCSID and encoding name

    Valid convert modes include:
         none :        perform no conversion
         inplace:      Convert the file in-place (creates a .bak with the old contents)
         dotutf8:      Create a new file that is UTF-8 (extension will be .utf8)

Installation

Simply download the latest ccsidguesser.jar from the Releases page.

Examples

Show the best guess CCSID for myfile.txt:

java -jar ccsidguesser.jar myfile.txt

Show the top 5 guesses for the CCSID and their corresponding encoding names:

java -jar ccsidguesser.jar myfile.txt  --show=top5 --format=enc

Automatically set myfile.txt's CCSID tag to match the best guess for the file's contents:

java -jar ccsidguesser.jar myfile.txt  --autofix

Convert myfile.txt to UTF-8 "in place":

java -jar ccsidguesser.jar myfile.txt --convert=inplace
