The bug was because that when using map()
function, it will parse the Text
Object as non-UTF string, by using the text.toString()
. If we output this string, it will show abnormal characters like 3704,Bala�iha,RUS,Moskova,132900
So the we need to know how to convert it to correct UTF String, and then use the StringTokenizer. At least the first step should be finding the proper UTF String...

It was so strange, I tried with another way
String s = new String(value.copyBytes(), "UTF-8");
System.out.println(s);
But it still fails. Then I tried to read the original city.txt file, I find that it shows abnormally, even with LibreOffice, maybe the file is corrupted?
Pending...

Not a bug, it's from the computer's code mechanism, so use a computer with many fonts and character sets installed.
