[OT] Reading Unicode Files
In my Struts application, when I load a Resource Bundle (Property file)
that has Unicode characters (\u1234) they get interpreted as single
characters. However, when I read a file using a FileInputStream the
Unicode characters get interpreted as a String "\u1234".
I know I am missing something basic, but I can not figure it out. Can
anyone please tell me what the Properties.load() method does that I am
not doing?
Thanks for any help you can provide.
Scott M.

The OP was asking about how to read properties files, which are pretty
much defined to be ISO-8859-1 with escape codes for out-of-charset
characters that look like this:
\u1234
Scott wasn't asking about how to read Unicode files (that's easy: use
set the content type properly)... he was asking about how to properly
read the escape sequences.

This code properly reads the unicode files in jsp and set in session
Properties prop = null;
if (session.getAttribute("Properties") == null) {
URL myURL = null;
myURL = application.getResource("/common/language/japanese_lang.properties");
String fnsKey;
String fnsVal;
InputStream is = myURL.openStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is, "UTF-8"));
prop = new Properties();
String fnsData;
fnsData = in.readLine();
while (fnsData != null) {
String fnsRetVal = "";
StringTokenizer stParse = new StringTokenizer(fnsData, "="); //breaking the string
while (stParse.hasMoreTokens()) {
fnsKey = stParse.nextToken().trim();
if (stParse.hasMoreTokens()) {
fnsVal = stParse.nextToken().trim();
prop.setProperty(fnsKey, fnsVal);
}
}
fnsData = in.readLine();
}
session.setAttribute("Properties", prop);
} else {
prop = (Properties) session.getAttribute("Properties");
}

java.util.Properties.load includes the interpretation of those \uWXYZ
codes, while you are probably not reading them in as such.
(ResourceBundle uses Properties.load or something exactly like it to
load PropertyResourceBundles).

They specifically look for \uWXYZ sequences and do their own conversion.
It's not a character encoding issue or anything like that... it's just
parsing and converting. You'll have to do it yourself.
Don't forget that if you have the JDK installed you can look at the Java
sources for just about any class. Try looking for JAVA_HOME/src.zip or
JAVA_HOME/share/src.zip and looking at the java.util.Properties source
code yourself.
