Kana iteration marks are are rarely used today, and hence there is not much online information on it besides this Wikipedia article, which leaves me with a couple questions.
- Is there any kana that cannot be expressed with an iteration mark? What about digraphs used in yōon, long vowels, or
んandン? - Can a kana with handakuten such as
ぷbe expressed with iteration marks? Presumably,ぷゝwith an unvoiced mark would be equivalent toぷふ, but what aboutぷゞwith a voiced one? Would it meanぷぷwith handakuten orぷぶwith dakuten?
Hoping someone will be able to help me better understand these unique symbols!
