My recommendation was based on the text in
screenshot in post 8. And it'll definitely work for
such files,
if you follow my instructions. Your screenshot shows this for
Глава 1 (= Chapter 1):
Code:
<p [...]>Глава 1</p>
The same string (with a Roman numeral one) can also be found in
my sample CP1251 epub.
After conversion from CP1251 to UTF-8 it'll become:
Code:
<p [...]>Глава 1</p>
Since you can't follow simple instructions, this'll be my last reply in this thread.
