I have installed Netbeans 6.0 on Mac OSX 10.4. When I try to System.out.println strings containing Japanese characters,
the characters display correctly in the source code, but are displayed as question marks in the output window.
Note that for instance German umlaut characters display fine.
see also 130117 filed on j2se project since was seen in doing in j2se project
but am thinking this is not limited to j2se project though
as mentioned in that issue, some multibyte appears ok in output window.
Works fine on Ubuntu (provided that you configure the project with UTF-8 encoding, or use Unicode escape sequences in
the source). Generally speaking, sending non-ASCII characters to standard output streams is highly dependent on your
operating system; it is outside of NetBeans' control. If you want it to work, Linux is your best bet, and generally you
will want your system to be configured to use UTF-8 encoding universally.
yes, understand its marked as wontfix; am asking for technical reasons why it won't or can't be
fixed for mac. that is, is it a known mac limitation or issue
or mac jdk one vs something in netbeans ? I think thats a fair kind of request when
issue is marked as wontfix.
The Java runtime in the user app translates characters to bytes when writing to a stream such as System.out, and
correspondingly translates bytes to characters when reading from the (misleadingly named) Process.getInputStream in NB
(or actually the Ant class which handles I/O for <java>). If in the first case the OS defines a platform encoding which
cannot represent some characters, it replaces them with '?'. Mac OS X, from what I recall (I have no access to a Mac to
verify), uses some funny encoding which is incapable of representing full Unicode; ditto Windows and Solaris; whereas
all modern Linux distributions use UTF-8 throughout and so have no such problem. Similar considerations apply to
filenames and other OS-visible strings: a Linux machine using an ext3 filesystem (normally interpreted as using UTF-8)
can trivially name a file with any Unicode characters, but on other OSs this will not work in many cases, depending on
implementation details of the JRE, and the particulars of the OS installation (e.g. Japanese Windows vs. American Windows).
