NAME

       unibmp2hex - Bitmap graphics file to GNU Unifont .hex file converter

SYNOPSIS

       unibmp2hex [-phexpage] [-iinput_file] [-ooutput_file] [-w]

DESCRIPTION

       unibmp2hex reads a bitmap produced by unihex2bmp before or after editing, and converts it back into a Unifont .hex format file.	The graph-
       ics file contains a block of 256 Unicode code points arranged in a 16 by 16 grid.  Each code point appears in a 32 by 32 pixel grid.  Char-
       acters are either 16 rows by 8 columns, or 16 rows by 16 columns.

OPTIONS

       -ppagenum   Specify  that  the  code points will be assigned to the 256 block space pagenum in the .hex file.  If not specified, unibmp2hex
		   will determine the appropriate block by reading the row and column headers.	Note that "page" is not a standard  Unicode  term.
		   It  refers  to  an output bitmap graphics page of 16 by 16 code points.  If pagenum is greater than FF, the block resides above
		   the Unicode Basic Multilingual Plane. In that event, the .hex file will contain eight digit hexadecimal code points rather than
		   the Unifont standard of four hexadecimal code points.

       -i	   Specify the input file. The default is stdin.

       -o	   Specify the output file. The default is stdout.

       -w	   Force all output .hex glyphs to be 16 pixels wide rather than dual width (8 or 16 pixels).

       Sample usage:

       unibmp2hex -imy_input_file.bmp -omy_output_file.hex

FILES

       *.bmp or *.wbmp graphics files

BUGS

       No  known  real	bugs exist, except that this software does not perform extensive error checking on its input files.  If they're not in the
       format of the original bitmapped output from unihex2bmp, all bets are off.

       If the output file is for a "page" containing space code points and the bitmap file squares for those code points are not empty, unibmp2hex
       preserve  the  graphics as they are drawn.  They will be removed later using uniunmask, with spaces of the appropriate width from a substi-
       tutes.hex file.

NAME

       punycode_decode - decode Punycode to Unicode

SYNOPSIS

       #include <punycode.h>

       int  punycode_decode(size_t  input_length,  const  char	[]  input,  size_t  *  output_length,  punycode_uint  []  output, unsigned char []
       case_flags);

ARGUMENTS

       size_t input_length
		   The number of ASCII code points in the input array.

       const char [] input
		   An array of ASCII code points (0..7F).

       size_t * output_length
		   The caller passes in the maximum number of code points that it can receive into the output array (which  is	also  the  maximum
		   number  of  flags that it can receive into the case_flags array, if case_flags is not a NULL pointer).  On successful return it
		   will contain the number of code points actually output (which is also the number of flags actually output, if case_flags is not
		   a  null  pointer).	The  decoder will never need to output more code points than the number of ASCII code points in the input,
		   because of the way the encoding is defined.	The number of code points output cannot exceed the maximum  possible  value  of  a
		   punycode_uint, even if the supplied output_length is greater than that.

       punycode_uint [] output
		   An array of code points like the input argument of punycode_encode() (see above).

       unsigned char [] case_flags
		   A NULL pointer (if the flags are not needed by the caller) or an array of boolean values parallel to the output array.  Nonzero
		   (true, flagged) suggests that the corresponding Unicode character be forced to uppercase by the caller (if possible), and  zero
		   (false,  unflagged) suggests that it be forced to lowercase (if possible).  ASCII code points (0..7F) are output already in the
		   proper case, but their flags will be set appropriately so that applying the flags would be harmless.

DESCRIPTION

       Converts Punycode to a sequence of code points (presumed to be Unicode code points).

RETURN VALUE

       The return value can be any of the Punycode_status values  defined  above.   If	not  PUNYCODE_SUCCESS,	then  output_length,  output,  and
       case_flags might contain garbage.
