<i>Ascii</i> prints the ASCII values corresponding to characters and
|
|
<i>vice versa</i>; under the <tt><font size=+1>−8</font></tt> option, the ISO Latin-1 extensions (codes
|
|
0200-0377) are included. The values are interpreted in a settable
|
|
numeric base; <tt><font size=+1>−o</font></tt> specifies octal, <tt><font size=+1>−d</font></tt> decimal, <tt><font size=+1>−x</font></tt> hexadecimal (the
|
|
default), and <tt><font size=+1>−b</font></tt><i>n</i> base <i>n</i>.
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
With no arguments, <i>ascii</i> prints a table of the character set in
|
|
the specified base. Characters of <i>text</i> are converted to their
|
|
ASCII values, one per line. If, however, the first <i>text</i> argument
|
|
is a valid number in the specified base, conversion goes the opposite
|
|
way. Control characters are printed as two- or three-character
|
|
mnemonics. Other options are:<br>
|
|
<tt><font size=+1>−n</font></tt> Force numeric output.<br>
|
|
<tt><font size=+1>−c</font></tt> Force character output.<br>
|
|
<tt><font size=+1>−t</font></tt> Convert from numbers to running text; do not interpret control
|
|
characters or insert newlines.
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
<i>Unicode</i> is similar; it converts between UTF and character values
|
|
from the Unicode Standard (see <a href="../man7/utf.html"><i>utf</i>(7)</a>). If given a range of hexadecimal
|
|
numbers, <i>unicode</i> prints a table of the specified Unicode characters
|
|
-- their values and UTF representations. Otherwise it translates
|
|
from UTF to numeric value or vice versa, depending
|
|
on the appearance of the supplied text; the <tt><font size=+1>−n</font></tt> option forces numeric
|
|
output to avoid ambiguity with numeric characters. If converting
|
|
to UTF , the characters are printed one per line unless the <tt><font size=+1>−t</font></tt>
|
|
flag is set, in which case the output is a single string containing
|
|
only the specified characters. Unlike <i>ascii</i>, <i>unicode</i> treats
|
|
no characters specially.
|
|
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
|
|
|
|
The output of <i>ascii</i> and <i>unicode</i> may be unhelpful if the characters
|
|
printed are not available in the current font.

The file <tt><font size=+1>/usr/local/plan9/lib/unicode</font></tt> contains a table of characters
|

and descriptions, sorted in hexadecimal order, suitable for <a href="../man1/look.html"><i>look</i>(1)</a>
|

on the lower case <i>hex</i> values of characters.<br>
