SYNOPSIS
unicode [options] string

DESCRIPTION
This manual page documents the unicode command.

unicode is a command line unicode database query tool.

OPTIONS

-h  --help

    Show help and exit.

-x  --hexadecimal

    Assume string to be a hexadecimal number

-d  --decimal

    Assume string to be a decimal number

-o  --octal

    Assume string to be an octal number

-b  --binary

    Assume string to be a binary number

-r  --regexp

    Assume string to be a regular expression

-s  --string

    Assume string to be a sequence of characters

-a  --auto

    Try to guess type of string from one of the above (default)

-mMAXCOUNT
    --max=MAXCOUNT

    Maximal number of codepoints to display, default: 20; use 0 for unlimited

-iCHARSET
    --io=IOCHARSET

    I/O character set. For maximal pleasure, run unicode on UTF-8 capable terminal and specify IOCHARSET to be UTF-8. unicode tries to guess this value from your locale, so with properly set up locale, you should not need to specify it.

--fcp=CHARSET
    --fromcp=CHARSET

    Convert numerical arguments from this encoding, default: no conversion. Multibyte encodings are supported. This is ignored for non-numerical arguments.

-cADDCHARSET
    --charset-add=ADDCHARSET

    Show hexadecimal reprezentation of displayed characters in this additional charset.

-CUSE_COLOUR
    --colour=USE_COLOUR

    USE_COLOUR is one of on off auto

    --colour=on will use ANSI colour codes to colourise the output

    --colour=off won't use colours.

    --colour=auto will test if standard output is a tty, and use colours only when it is.

    --color is a synonym of --colour

-v  --verbose

    Be more verbose about displayed characters, e.g. display Unihan information, if available.

-w  --wikipedia

    Spawn browser pointing to English Wikipedia entry about the character.

--wt
    --wiktionary

    Spawn browser pointing to English Wiktionary entry about the character.

--brief

    Display character information in brief format

--format=fmt

    Use your own format for character information display. See the README for details.

--list

    List (approximately) all known encodings.

--ascii

    Display ASCII table

--brexit-ascii
    --brexit

    Display ASCII table (EU–UK Trade and Cooperation Agreement 2020 version)

USAGE

unicode tries to guess the type of an argument. In particular, if the arguments looks like a valid hexadecimal representation of a Unicode codepoint, it will be considered to be such. Using

unicode face

will display information about U+FACE CJK COMPATIBILITY IDEOGRAPH-FACE, and it will not search for 'face' in character descriptions - for the latter, use:

unicode -r face

For example, you can use any of the following to display information about U+00E1 LATIN SMALL LETTER A WITH ACUTE (á):

unicode 00E1

unicode U+00E1

unicode á

unicode 'latin small letter a with acute'

You can specify a range of characters as argumets, unicode will show these characters in nice tabular format, aligned to 256-byte boundaries. Use two dots ".." to indicate the range, e.g.

unicode 0450..0520

will display the whole cyrillic and hebrew blocks (characters from U+0400 to U+05FF)

unicode 0400..

will display just characters from U+0400 up to U+04FF

Use --fromcp to query codepoints from other encodings:

unicode --fromcp cp1250 -d 200

Multibyte encodings are supported: unicode --fromcp big5 -x aff3

and multi-char strings are supported, too:

unicode --fromcp utf-8 -x c599c3adc5a5

BUGS
Tabular format does not deal well with full-width, combining, control and RTL characters.
