NAME
ascii, unicode – interpret ASCII, Unicode characters |
SYNOPSIS
ascii [ –8cnt ] [ –dox | –b n ] [ text ] unicode hexmin–hexmax unicode [ –t ] hex [ ... ] unicode [ –n ] characters
look hex /lib/unicode |
DESCRIPTION
Ascii prints the ASCII values corresponding to characters and
vice versa; under the –8 option, the ISO Latin–1 extensions (codes
0200–0377) are included. The values are interpreted in a settable
numeric base; –o specifies octal, –d decimal, –x hexadecimal (the
default), and –bn base n.
With no arguments, ascii prints a table of the character set in
the specified base. Characters of text are converted to their
ASCII values, one per line. If, however, the first text 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: Unicode is similar; it converts between UTF and character values from the Unicode Standard (see utf(6)). If given a range of hexadecimal numbers, unicode 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 –n option forces numeric output to avoid ambiguity with numeric characters. If converting to UTF , the characters are printed one per line unless the –t flag is set, in which case the output is a single string containing only the specified characters. Unlike ascii, unicode treats no characters specially. The output of ascii and unicode may be unhelpful if the characters printed are not available in the current font.
The file /lib/unicode contains a table of characters and descriptions,
sorted in hexadecimal order, suitable for look(1) on the lower
case hex values of characters. |
