 54 cfa37a7b 2004-04-10 devnull Latin-1 extensions (codes 0200-0377) are included.
 55 cfa37a7b 2004-04-10 devnull The values are interpreted in a settable numeric base;
 56 cfa37a7b 2004-04-10 devnull .B -o
 57 cfa37a7b 2004-04-10 devnull specifies octal,
 58 cfa37a7b 2004-04-10 devnull .B -d

 66 cfa37a7b 2004-04-10 devnull With no arguments,
 67 cfa37a7b 2004-04-10 devnull .I ascii
 68 cfa37a7b 2004-04-10 devnull prints a table of the character set in the specified base.
 69 cfa37a7b 2004-04-10 devnull Characters of
 70 cfa37a7b 2004-04-10 devnull .I text
 71 cfa37a7b 2004-04-10 devnull are converted to their
 72 cfa37a7b 2004-04-10 devnull .SM ASCII 
 73 cfa37a7b 2004-04-10 devnull values, one per line. If, however, the first
 74 cfa37a7b 2004-04-10 devnull .I text
 75 cfa37a7b 2004-04-10 devnull argument is a valid number in the specified base, conversion
 76 cfa37a7b 2004-04-10 devnull goes the opposite way.
 77 cfa37a7b 2004-04-10 devnull Control characters are printed as two- or three-character mnemonics.

 90 cfa37a7b 2004-04-10 devnull .I Unicode
 91 cfa37a7b 2004-04-10 devnull is similar; it converts between
 92 cfa37a7b 2004-04-10 devnull .SM UTF
 93 cfa37a7b 2004-04-10 devnull and character values from the Unicode Standard (see

 99 cfa37a7b 2004-04-10 devnull representations.
100 cfa37a7b 2004-04-10 devnull Otherwise it translates from
101 cfa37a7b 2004-04-10 devnull .SM UTF
102 cfa37a7b 2004-04-10 devnull to numeric value or vice versa,
103 cfa37a7b 2004-04-10 devnull depending on the appearance of the supplied text;
104 cfa37a7b 2004-04-10 devnull the
105 cfa37a7b 2004-04-10 devnull .B -n
106 cfa37a7b 2004-04-10 devnull option forces numeric output to avoid ambiguity with numeric characters.
107 cfa37a7b 2004-04-10 devnull If converting to
108 cfa37a7b 2004-04-10 devnull .SM UTF ,
109 cfa37a7b 2004-04-10 devnull the characters are printed one per line unless the
110 cfa37a7b 2004-04-10 devnull .B -t
111 cfa37a7b 2004-04-10 devnull flag is set, in which case the output is a single string
112 cfa37a7b 2004-04-10 devnull containing only the specified characters.
113 cfa37a7b 2004-04-10 devnull Unlike
114 cfa37a7b 2004-04-10 devnull .IR ascii ,
115 cfa37a7b 2004-04-10 devnull .I unicode
116 cfa37a7b 2004-04-10 devnull treats no characters specially.
