I have a signed string like this: "Làm sao để chuyển chuổi có dấu về không dấu?"
And I want to translate it to string like this: "Lam sao de chuyen chuoi co dau ve khong dau?"
Please tell me the way to solve it in Java code. Thanks a lot!

Something like
public static void main(String args[]) {
String src = "Làm sao để chuyển chuổi có dấu về không dấu?";
String dest = Normalizer.normalize(src, Normalizer.Form.NFD);
dest = dest.replaceAll("[^\\p{ASCII}]", "");
System.out.println(src);
System.out.println(dest);
}
gives you
Làm sao để chuyển chuổi có dấu về không dấu?
Lam sao e chuyen chuoi co dau ve khong dau?

I just noticed that this doesn't quite give you what you require: để has been truncated to e.

It looks like the problem isn't that simple: there's a similar question here stackoverflow.com/questions/2362810/…

Yeah, that's not simple. But thanks a lot Jonathan, I'll follow your suggestion. :)

Would you please explain to me the meaning of this characters "[^\\p{ASCII}]" ?

replaceAll takes a regular expression, you can see details here: docs.oracle.com/javase/1.5.0/docs/api/java/util/regex/… -- here is means to match anything that's not an ASCII character. The call to Normalizer.normalize decomposes characters with accents in to separate ASCII-character + Unicode combining accent-character, so when we filter out non-ASCII we have almost the string we want. Except đ doesn't seem to have an alternative ASCII+combining accent representation, so we end up removing it completely.
