I find that these 'Japanese-only' Kanji fascinating. I can only take a glimpse of its meaning through the parts. I take that these must be obscure characters since it's included in "Ghost Kanji Characters". I couldn't find these characters in Chinese Dictionary either even though these are considered "Kanjis".
Here are my questions:
1.What are the usages and word-pairs/collocation or sentence example that represent the meaning(s) of these Kanji? How do you use it? How often?
2.As a native Japanese or a foreigner who lives for the longest time in Japan, have you used (or at least tried to use) these kanjis?
3.Is its usage only limited to research or linguistics study?
4.What does "S&H uses jabberwocky words" mean? Does it mean a ** nonsensical language aka nonsense word**? (what is 'S&H?')
5.Are all my assumptions correct? I mean the misintended character? Did I miss something?
