Two SWING apps show different UNICODE bahaviour

Question

We have developed two SWING applications. In both of them we save information by writing to disk using UTF-8 format. When the files are read back and displayed using JTextField then one of the applications is able to display the (Bengali) characters properly but the other applications is displaying garbage.
We are using Java (JRE) version 1.5.0_01. The Unicode font (Likhan.ttf) is kept under the directory "JRE/lib/font/fallback". The files written to disk are text (XML) files.
Any idea what we might be doing differently in one application from the other?

Answer 1

UNIX ?
1. check user locale
it should be xx_XX.UTF-8. xx_XX - doesn't matter, but UTF-8 is important.
e.g.
LANG="en_EN.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_ALL=
2. try to compile you class with -encoding utf-8 option
javac -encoding utf-8 Your.java
3. try to output some text in Bengali to JTextField directly from code to understand where exactly the problem arise.
4. check system property file.encoding
class Enc {
     public static void main(String[] args) {
          System.out.println(System.getProperty("file.encoding"));
}how do you read data from file? do you specify encoding directly?
