	43 .SH DESCRIPTION
	44 .I Ascii
	45 prints the
	46 .SM ASCII
	47 values corresponding to characters and
	48 .I vice
	49 .IR versa ;
	50 under the
	51 .B -8
	52 option, the
	53 .SM ISO
	54 Latin-1 extensions (codes 0200-0377) are included.
	55 The values are interpreted in a settable numeric base;
	56 .B -o
	57 specifies octal,
	58 .B -d
	59 decimal,
	60 .B -x
	61 hexadecimal (the default), and
	62 .BI -b n
	63 base
	64 .IR n .
	65 .PP
	66 With no arguments,
	67 .I ascii
	68 prints a table of the character set in the specified base.
	69 Characters of
	70 .I text
	71 are converted to their
	72 .SM ASCII
	73 values, one per line. If, however, the first
	74 .I text
	75 argument is a valid number in the specified base, conversion
	76 goes the opposite way.
	77 Control characters are printed as two- or three-character mnemonics.
	78 Other options are:
	79 .TP
	80 .B -n
	81 Force numeric output.
	82 .TP
	83 .B -c
	84 Force character output.
	85 .TP
	86 .B -t
	87 Convert from numbers to running text; do not interpret
	88 control characters or insert newlines.
	89 .PP
	90 .I Unicode
	91 is similar; it converts between
	92 .SM UTF
	93 and character values from the Unicode Standard (see
	94 .IR utf (7)).
	95 If given a range of hexadecimal numbers,
	96 .I unicode
	97 prints a table of the specified Unicode characters \(em their values and
	98 .SM UTF
	99 representations.
	100 Otherwise it translates from
	101 .SM UTF
	102 to numeric value or vice versa,
	103 depending on the appearance of the supplied text;
	104 the
	105 .B -n
	106 option forces numeric output to avoid ambiguity with numeric characters.
	107 If converting to
	108 .SM UTF ,
	109 the characters are printed one per line unless the
	110 .B -t
	111 flag is set, in which case the output is a single string
	112 containing only the specified characters.
	113 Unlike
	114 .IR ascii ,
	115 .I unicode
	116 treats no characters specially.
	117 .PP
	118 The output of
	119 .I ascii
	120 and
	121 .I unicode
	122 may be unhelpful if the characters printed are not available in the curr…
	123 .PP
	124 The file
	125 .B \*9/lib/unicode
	126 contains a
	127 table of characters and descriptions, sorted in hexadecimal order,
	128 suitable for
	129 .IR look (1)
	130 on the lower case
	131 .I hex
	132 values of characters.
	133 .SH EXAMPLES
	134 .TP
	135 .B "ascii -d"
	136 Print the
	137 .SM ASCII
	138 table base 10.
	139 .TP
	140 .B "unicode p"
	141 Print the hex value of `p'.
	142 .TP
	143 .B "unicode 2200-22f1"
	144 Print a table of miscellaneous mathematical symbols.
	145 .TP
	146 .B "look 039 \*9/lib/unicode"
	147 See the start of the Greek alphabet's encoding in the Unicode Standard.
