I have been using latest icu4j version. When trying to convert english number to Japanese or thai number, iam getting english number.

BigDecimal number = new BigDecimal("123.22");
Locale locale = new Locale("th"); //Thai
NumberFormat dsa = NumberFormat.getInstance(locale);
dsa.format(number);

Expected O/P: ๑๒๓.๒๒
Output received: 123.22
