After struggling finally i found solution.
//String that you want to convert
String mystring = "133 Phùng Hưng, Cửa Đông, Hoàn Kiếm, Hà Nội, Vietnam";
//unicodeString is the expected output in unicode
String unicodeString = getUnicodeString(escapeUnicodeText(mystring));
//i want to make small u into Capital from unicode String
String resultUnicode = unicodeString.replace("\\u", "\\U");
try {
String text = URLEncoder.encode(mystring, "UTF-8");
Log.v("currentDateTimeString", "text String:" + text);
} catch (Exception e) {
e.printStackTrace();
}
Create method escapeUnicodeText to get your Unicode Text into unicode fromat for example if you pass input string ♫ é in escapeUnicodeText() you will get in unicode output like \u266b \u00e9
public String escapeUnicodeText(String input) {
StringBuilder b = new StringBuilder(input.length());
java.util.Formatter f = new java.util.Formatter(b);
for (char c : input.toCharArray()) {
if (c < 128) {
b.append(c);
} else {
f.format("\\u%04x", (int) c);
}
}
return b.toString();
}
Pass output of escapeUnicodeText into getUnicodeString() you will get your expected result like \U0111\U01b0\U1eddng \U0110\U1eadp, Th\U00f4ng T\U1ef1, T\U00f9ng \U1ea2nh, \U0110\U1ee9c Th\U1ecd, H\U00e0 T\U0129nh, Vietnam.
public String getUnicodeString(String myString) {
String text = "";
try {
byte[] utf8Bytes = myString.getBytes("UTF8");
text = new String(utf8Bytes, "UTF8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return text;
}
