It is a bug

[dayAndnight2018]

When I input an English sentence, it looks like this:

I think it is a bug to translate "I" to the order symbol "i."

thanks for report.

To fix this issue, I have to make the rule of list markers strict.

In particular

1. roman number order must start with 'i,' ～ 'iii,'. and disallow other character than [cdilmvx].
2. alphabet order must start with 'a,' ～ 'c,'. and, in grammatically, list markers with two or more characters are disallowd (display is allowed).

I will reclose after release
