-
-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.

--fromcp=CHARSET
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.

--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

if available.

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.
