The specific problem with the "И" character happens when deliberately using cp1251 when converting the bytes or setting the default it via -Dfile.encoding=cp1251:

String s = "";
for (char ch = 0x0410; ch <= 0x044F; ch++)
    s += ch;

String s2 = s;

System.out.println(Charset.defaultCharset());

System.out.println(s);
s = new String(s.getBytes("utf-8"));
System.out.println(s);
s = new String(s.getBytes(), "utf-8");
System.out.println(s);

System.out.println(s2);
s2 = new String(s2.getBytes("utf-8"), "cp1251");
System.out.println(s2);
s2 = new String(s2.getBytes("cp1251"), "utf-8");
System.out.println(s2);

This kind of invalid byte/string conversion between cp1251 and utf-8 might explain this ... So at least this happens in this little test case.

How/where this can occur inside your or potentially any other ZK application I hope to find out with your stack trace.

I quite like those kind of mysteries so hang in.
