Show help and exit.
Assume string to be a hexadecimal number
Assume string to be a decimal number
Assume string to be an octal number
Assume string to be a binary number
Assume string to be a regular expression
Assume string to be a sequence of characters
Try to guess type of string from one of the above (default)
Maximal number of codepoints to display, default: 20; use 0 for unlimited
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.
Convert numerical arguments from this encoding, default: no conversion. Multibyte encodings are supported. This is ignored for non-numerical arguments.
Show hexadecimal reprezentation of displayed characters in this additional charset.
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
Be more verbose about displayed characters, e.g. display Unihan information, if available.

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

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