Actually, I have noticed one problem that so far is a mystery to me.
Somehow under Linux (with JDK 1.2.2) something seems to get lost when
trying to write to an OutputStreamWriter with a specified encoding, if
the string is not iso-8859-1, but my machine is. Sun has some sample
code on their I18N (actually, the very last example) that I cannot get
to work on Linux. No idea why, and I spent many many hours trying to
figure it out.
The code is supposed to write some Japanese String (in \unnn notation)
to an OutputStreamWriter, like:
OutputStreamWriter out = new OutputStreamWriter (new
FileOutPutStream("test.txt"), "UTF8");
out.write("\u672c\u8a9e");
Then the code is supposed to read from that test.txt file by doing the
reverse, with an InputStreamWriter that specifies the encoding. There's
no way I could get this to work; my pretty Japanese string gets
completely garbled, no matter what encoding I specify, including if I
don't specify one at all (in which case it would use 8859_1.
So far, I've only succeeded in writing a shift-jis file, for example, by
doing something like
byte[] testArray = testString.getBytes("SJIS") and then writing that
array directly to a FileOutputStream (again starting with a testString
in \unnnn notation).
So maybe someone here knows what could be going on under the covers??
