Sorry, yes a typo. I meant ISO8859-1.
re: new String(byte[])
- read the javadoc for this. It builds a String using the current
System.getProperty("file.encoding")
In generaly, you should *always* specify the encoding that you want when
making a String from bytes - unless what you really want is the default
file.encoding for the JVM.
For example - if you start a generic JVM using the "java" command, the
default file.encoding is IBM-1047 (EBCDIC).
But, Websphere and many other Java apps will run with
file.encoding=ISO8859-1.
This is because there are many libraries that incorrectly use the default
file.encoding (like new String(byte[])), but assume that they are working
in ASCII.
So, its just easier to run the JVM with file.encoding = ISO8859-1 to avoid
issue.
Then, you have to remember to specify that you want EBCDIC with you are
working with external EBCDIC resources.
Remember that Strings in Java are UTF-16.
