uni

NAME

uni - display Unicode character information

SYNOPSIS

uni [option]... [character]...

DESCRIPTION

Displays information about Unicode characters.

In the absence of a name match option, each character option can independently be any one of:

• a single character;
• an integer code point number;
• a character name;
• the form U+hexdigits.

NAME MATCH OPTIONS

--egrep, -e

The character arguments are extended regular expressions, matched against character names.

--glob, -g

The character arguments are shell-style patterns, matched against character names.

--html, -H

The character arguments are HTML entity names. Surrounding the name with & and ; is optional.

--match, -m

The character arguments are text that can match anywhere in a character name.

--string, -S

The character arguments are treated as sequences of individual characters. For example, if the argument is tilde, instead of reporting the single character ~, the result will be the five characters t, i, l, d, and e.

--word, -w

The character arguments are full words that must appear in a character name.

BLOCK MATCH OPTION

--block=block, -b block

Limits matches to characters within the given block(s). (Unlike other match options, this is always restrictive even with --any.) A block can be a Unicode block name. It can also be any of the character forms, designating the block containing that character.

PROPERTY MATCH OPTIONS

Currently, these are not user-friendly; the argument must exactly match the form returned by Python unicodedata.

• --bidi=bidi
• --category=category
• --combining=combining
• --decimal=decimal
• --decomposition=decomposition
• --digit=digit
• --mirrored=mirrored
• --numeric=numeric
• --width=width

GENERAL MATCH OPTIONS

--all

Given multiple match conditions, all must apply in order for a character to be selected. This is the default.

--any, -a

Given multiple match conditions, any single match is sufficient for a character to be selected.

FORMAT OPTIONS

--format=format, -f format

Print according to a format string. The string may contain keywords surrounded by curly braces, and other text printed as-is.

The keywords are:

• {bidirectional} - the character's bidirectional class.
• {block} - the name of the block containing the character.
• {category} - the character's category.
• {char} - the character.
• {combining} - the character's combining value.
• {decimal} - the character's decimal value.
• {decomposition} - the character's decomposition.
• {digit} - the character's digit value.
• {eol} - the end-of-line character (newline unless changed by command-line options).
• {html} - the HTML entity name for the character.
• {id} - the character name with blanks and hyphends replaced by _.
• {mirrored} - whether the character is mirrored in bidirectional text.
• {name} - the character's name.
• {nfc} - the NFC normalization form, as character names.
• {NFC} - the NFC normalization form.
• {nfd} - the NFD normalization form, as character names.
• {NFD} - the NFD normalization form.
• {nfkc} - the NFKC normalization form, as character names.
• {NFKC} - the NFKC normalization form.
• {nfkd} - the NFKD normalization form, as character names.
• {NFKD} - the NFKD normalization form.
• {numeric} - the character's numeric value.
• {ordinal} - the character's code point number.
• {utf8} - the UTF-8 encoding of the character, as a sequence of two-digit hexadecimal numbers.
• {utf16} - the UTF-16 encoding of the character, as one or two four-digit hexadecimal numbers.
• {u} - the code point number, in the form U+hexdigits.
• {un} - as {u}, but zero-padded to at least n digits.
• {v} - the code point number, in decimal.
• {width} - the character's width class (‘East Asian width’).
• {x} - the code point number, in hexdecimal (with no prefix).

--char

Print the character alone. Equivalent to --format '{char}'.

--compose

Print in a form useful in XCompose files. Equivalent to --format ': "{char}" U{x} # {name}'.

--long

Print full details about the character

--name

Print the character name. Equivalent to --format '{name}'.

--short

Print the character, code, and name. This is the default. Equivalent to --format '{char} {u} {name}'.

SEPARATOR OPTIONS

--nonewline, -n

Do not print a newline between output for different characters.

--separator=eol, -s eol

Print eol between output for different characters.

--null, -0

Print an ASCII NUL between output for different characters.
