+Uniset -- Unicode subset manager -- Markus Kuhn
+
+Uniset merges and subtracts Unicode subsets. It can output and
+analyse the resulting character set in various formats.
+
+Uniset understand the following command-line arguments:
+
+Commands to define a set of characters:
+
+ + filename add the character set described in the file to the set
+ - filename remove the character set described in the file from the set
+ +: filename add the characters in the UTF-8 file to the set
+ -: filename remove the characters in the UTF-8 file from the set
+ +xxxx..yyyy add the range to the set (xxxx and yyyy are hex numbers)
+ -xxxx..yyyy remove the range from the set (xxxx and yyyy are hex numbers)
+ +cat=Xx add all Unicode characters with category code Xx
+ -cat=Xx remove all Unicode characters with category code Xx
+ -cat!=Xx remove all Unicode characters without category code Xx
+ clean remove any elements that do not appear in the Unicode database
+ unknown remove any elements that do appear in the Unicode database
+
+Command to output descriptions of the constructed set of characters:
+
+ table write a full table with one line per character
+ compact output the set in compact MES format
+ c output the set as C interval array
+ nr output the number of characters
+ sources output a table that shows the number of characters contributed
+ by the various combinations of input sets added with +.
+ utf8-list output a list of all characters encoded in UTF-8
+
+Commands to tailor the following output commands:
+
+ html write HTML tables instead of plain text
+ ucs add the unicode character itself to the table (UTF-8 in
+ plain table, numeric character reference in HTML)
+
+Formats of character set input files read by the + and - command:
+
+Empty lines, white space at the start and end of the line and any
+comment text following a \# are ignored. The following formats are
+recognized
+
+xx yyyy xx is the hex code in an 8-bit character set and yyyy
+ is the corresponding Unicode value. Both can optionally
+ be prefixed by 0x. This is the format used in the
+ files on <ftp://ftp.unicode.org/Public/MAPPINGS/>.
+
+yyyy yyyy (optionally prefixed with 0x) is a Unicode character
+ belonging to the specified subset.
+
+yyyy-yyyy a range of Unicode characters belonging to
+yyyy..yyyy the specified subset.
+
+xx yy yy yy-yy yy xx denotes a row (high-byte) and the yy specify
+ corresponding low bytes or with a hyphen also ranges of
+ low bytes in the Unicode values that belong to this
+ subset. This is also the format that is generated by
+ the compact command.
