NAME

       unijohab2html - Show combined Hangul syllable jamo juxtaposition as a web page

SYNOPSIS

       unijohab2html -i hangul-base.hex -o hangul-syllables.hex

DESCRIPTION

       unijohab2html  reads  glyphs  in  a  Unifont  .hex  file  organized  in  a Johab 6/3/1 format (6 choseong
       variations, 3 jungseong variations, and 1 jongseung variation).  It then produces  an  HTML  output  file
       showing all Hangul letters in a color-coded output in 16-by-16 cell grids: blue cells show where choseong
       glyphs appear; green for jungseong; and red for jongseong.

       Any overlaps are shown with a combination of the colors.   For example, where one or more choseong (blue)
       letters  overlap jungseong (green), the associated cell will be blue + green = cyan.  Likewise, jungseong
       (green) and jongseong (red) overlaps will appear as green + red = yellow, etc.  There is a color  key  at
       the beginning of the HTML table.

       If  any  overlaps of choseong and jungseong exist, these will then be output in the HTML file identifying
       the overlapping letters in a combined Unifont .txt file format.   From  these  overlaps,  a  Hangul  font
       creator can decide whether the overlap is acceptable or should be modified.

       If  an  overlap is with an ancient vowel or diphthong (i.e., U+1176, HANGUL JUNGSEONG A-O through U+11A7,
       HANGUL JUNGSEONG O-YAE), it is marked as an "Ancient Vowel" in  this  ending  list  of  overlaps.   If  a
       choseong  is  ancient  (i.e.,  U+11C3,  HANGUL  JONGSEONG  KIYEOK-RIEUL, through U+11FF, HANGUL JONGSEONG
       SSANGNIEUN), it is marked as "Ancient Choseong" in the output.  Overlapping choseong and jungseong in the
       Hangul Jamo Extended-A and Extended-B ranges are listed as "Extended Ancient".   This  identification  of
       ancient  and  extended  ancient versus modern Hangul will allow a font designer to optimize modern Hangul
       when weighing design tradeoffs.
