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

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.
