Please help!
But currently I don’t use EPUB or LaTeX.
Some programing language including Python 3 can use non US-ASCII characters to name identifiers.
This means all functions, methods, valuables, classes, or so on, should be available to accept Yomigana.
index role and index directive should be also.
This is not major case, but possible the reason historical, political or etc.
For the words very difficult to read, and only for the words, we want to show readers both the term and its Yomigana.
Currently, we can use The Term (Yomigana) form, the term contains yomigana. But in this way, Yomigana should be written twice and sorting may be inaccurate a bit.
