utf8

utf8 provides unicode code point values for input runes and the unicode rune (if printable) for a given unicode code point.

With no arguments, prints a table of unicode code points in the range [-from, -to] in the style of ascii(1).

By default, table output suppresses non-printable characters (toggled by -g).

A one-element-per-line list useful for scripting can be emitted with -l.
