SYNOPSIS
rune/block rune ...
rune/case [ ltu ] [ -f file ]
rune/compose [ file ... ]
rune/fold [ -i ] [ file ... ]
rune/type [-x] [ file ... ]
rune/uconv [ -f ] [ -n defsize ] [ file ... ]
rune/unfold [ re ... ]
DESCRIPTION
These programs provide transformations on runes. Block con-
verts from rune to the containing Unicode block name. If
there exists a case conversion from the given rune, case
converts to the specified case. The ltu flags convert to
lower, title and upper case, respectively. The default is
lower case. If there exists an equivalent precombined code-
point, compose combines base codepoints with any following
combining codepoints. Fold converts codepoints to their
base codepoint, esentially stripping combining characters
while unfold transforms a regular expression to one that
matches any string which would match the original expression
if folded first. Both accept -i which makes the conversion
case insensitive. Type prints the codepoint then the type
classes of each given rune, which may be any of alpha,
title, space, lower, upper, and digit. Upper- and lowercase
append the type with a string consisting of a colon, the
corresponding lower- or upper case rune and the codepoint in
parenthesis. Digit values are followed by a colon and the
corresponding digit value. For example
03b1 alpha lower:Α(0391)
Uconv converts (4 hex digits) and (6 hex digits) to corre-
sponding runes. With the -f flag, it is assumed that the
escapes are terminated by non-numbers so the number of dig-
its is not checked while -n sets the default width. For
example, one could simulate the output of unicode (see
ascii(1)) with
awk 'BEGIN{for(i=945; i<955; i++)printf "\\u%.4x", i}' |

BUGS
Still a bit raw. Type has wierd output. It's not clear
that uconv does the most useful conversions.
