NAME

       geniconvtbl - generate iconv code conversion tables

SYNOPSIS

       geniconvtbl [-fnq] [-p preprocessor] [-W arg] [-Dname] [-Dname=def] [-Idirectory] [-Uname] [infile...]

DESCRIPTION

       The geniconvtbl utility accepts code conversion rules defined in flat text file(s) and writes code conversion binary table file(s) that can
       be used to support user-defined iconv code conversions (see iconv(1) and iconv(3C) for more detail on the iconv code conversion).

OPTIONS

       The following options are supported:

       -f		       Overwrites output file if the output file exists.

       -n		       Does not generate an output file. This is useful to check the contents of the input file.

       -p preprocessor	       Uses specified preprocessor instead of the default		  preprocessor, /usr/lib/cpp.

       -q		       Quiet option. It suppresses warning and error messages.

       -W arg		       Passes the argument arg to the preprocessor. If this option is specified more than once, all arguments  are  passed
			       to the preprocessor.

       -Dname		       geniconvtbl recognizes these options and passes them and their arguments to the preprocessor.
       -Dname=def
       -Idirectory
       -Uname

OPERANDS

       The following operand is supported:

       infile		       A  path name of an input file. If no input file is specified, geniconvtbl reads from the standard input stream. The
			       user can specify more than one input file if necessary.

OUTPUT

       If input is from the standard input stream, geniconvtbl writes output to the standard output stream. If one or more input files are  speci-
       fied,  geniconvtbl  reads from each input file and writes to a corresponding output file. Each of the output file names will be the same as
       the corresponding input file with .bt appended.

       The generated output files must be moved to the following directory prior to using the code conversions at iconv(1) and iconv(3C):

	      /usr/lib/iconv/geniconvtbl/binarytables/

       The output file name should start with one or more printable ASCII characters as the 'fromcode' name followed  by  a  percentage  character
       (%),  followed  by  one	or more printable ASCII characters as the 'tocode' name, followed by the suffix '.bt'. The 'fromcode' and 'tocode'
       names are used to identify the iconv code conversion at iconv(1) and iconv_open(3C)). The properly named output file should  be	placed	in
       the directory, /usr/lib/iconv/geniconvtbl/binarytables/.

EXAMPLES

       Example 1: Generating an iconv code conversion binary table

       The following example generates a code conversion binary table with output file name convertA2B.bt:

       example% geniconvtbl convertA2B

       Example 2: Generating multiple iconv code conversion binary tables

       The following example generates two code conversion binary tables with output files test1.bt and test2.bt:

       example% geniconvtbl test1 test2

       Example 3: Using another preprocessor

       The following example generates a code conversion binary table once the specified preprocessor has processed the input file:

       example% geniconvtbl -p /opt/SUNWspro/bin/cc -W -E convertB2A

       Example 4: Placing a binary table

       To  use	the  binary table created in the first example above as the engine of the conversion 'fromcode' ABC to 'tocode' DEF, become super-
       user and then rename it and place it like this:

       example# mv convertA2B.bt 
	   /usr/lib/iconv/geniconvtbl/binarytables/ABC%DEF.bt

       Example 5: Providing modified ISO8859-1 to UTF-8 code conversion

       Write  a  geniconvtbl  source  file  that  defines  the	code  conversion.  For	instance,  you	can  copy  over    /usr/lib/iconv/genicon-
       vtbl/srcs/ISO8859-1_to_UTF-8.src  into	  your	directory  and make necessary changes at the source file. Once the modifications are done,
       generate the binary table:

       example% geniconvtbl ISO8859-1_to_UTF-8.src

       As super-user, place the generated binary table with a unique name at the system directory where iconv_open(3C) can find the binary table:

       example su
       Password:
       example% cp ISO8859-1_to_UTF-8.bt 
	   /usr/lib/iconv/geniconvtbl/binarytables/my-iso-8859-1%utf-8.bt

       After that, you can do the iconv code conversion. For instance:

       example% iconv -f my-iso-8859-1 -t utf-8 testfile.txt

ENVIRONMENT VARIABLES

       1	Command line options are not correctly used or an unknown command line option was specified.

       2	Invalid input or output file was specified.

       3	Conversion rules in input files are not correctly defined.

       4	Conversion rule limit of input files has been reached. See NOTES section of geniconvtbl(4).
