unicode
UNICODE(1) General Commands Manual UNICODE(1) NAME
unicode - command line unicode database query tool 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 -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. -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 Wikipedia entry about the character. USAGE
unicode tries to guess the type of an argument. For example, you can use any of the following to display information about U+00E1 LATIN SMALL LETTER A WITH ACUTE (a): unicode 00E1 unicode U+00E1 unicode a 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 bound- aries. 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 BUGS
Tabular format does not deal well with full-width, combining, control and RTL characters. SEE ALSO
