With no FILE, read standard input. With no OPTION, recognize and write converted text to standard output.

-p, --print-charset

Print the name of the charset that suits best the input file.

-P, --print-all-charset

Print ranked list of charsets. The first column is the mark with locale bonus (language and system), the second is the mark brut, the third is the checksum of all extended character (to know which charsets produce the same results) and the fourth is the charset name (on the same line if their mark with bonus and their checksum are identical). If the recognition is sure (ASCII or UTF-8), print only one name.

-f, --from

Force input charset (disable recognition) and/or EOL. For instance, "UTF-8/CRLF".

-t, --to

Select output charset and/or EOL. See above.

-L, --language

Select language. All charsets that fit this language will get a bonus during recognition. If none specified, LC_* variables are used.

-S, --system

Select system. All charsets that fit this language will get a bonus during recognition.

-x, --ext-chars

Print lines with extended characters (try to print each extended character not more than once).

-d, --distribution

Print distribution, i.e. the count of each 8bits character.

-a, --all-ext-chars

Print each extended character of the file in each different charset (UTF-8 output is recommended).

-c, --colors

(with -x or -a) Use color.

-b, --bar

Display a progress bar.

-i, --info

Print default/chosen parameters.

-l, --list

List charsets/eol/languages/systems.

-h, --help Print some help.

-v, --version

Print version.

charset.dat

This file should be located in /usr/local/share/utrac/ or /usr/share/utrac/. It contains informations about charsets and their related charmap. If you want to add new charsets (they must be 8bits and ASCII compatible), check the script merge.pl in Utrac source directory.
