I am trying to find a workaround for displaying old and rare characters in Unicode using character combination. I am currently converting some dictionaries from EPWING to text, and there are 36 different characters that cannot be played using regular UTF-8. The following is the epwing gaiji problem section for single-code comparisons for one of the dictionaries that I am converting, in some areas it has an interesting syntax that is explicitly used to combine characters in different ways. I was hoping that someone could determine what the syntax was and where I could find documentation or a tutorial on how to use it.
