JSOP how to parse element with space and Cyrillic in id?

Question

Java

I iterate over the table:

for (Element element3 : element.select("th[id=Д-8 ]"))

In Intelji IDEA, it worked as it should, finding all elements with the specified id. But it doesn't work in the studio. (just finds th)
I suspect that the problem is due to the fact that "D" is Cyrillic. Or the gap interferes .. I can’t figure it out ..
Maybe someone came across?
UDP did a search just th, displayed id, they are without a karabzayak, everything is fine .. and a space is in place ..
The encoding is UTF-8

Answer 1

UDP has done this so far:

for (Element element3 : element.select("th"))
                    {
                        text = element3.attr("id"); 
                        if(text.indexOf("Д-8") != -1){}
}

Works.
