What problems do you actually have with MacRoman? If you aren't
running into it's probably a 'if it ain't broke don't fix it'
situation isn't it? It's a risky change since you might mess
things up for all jvm's. If it doesn't fix a problem why do it?
I don't think there is a way to change this for the scope you
want. If there were it would probably be located in a properties
file somewhere like
/System/Library/Frameworks/JavaVM.framework/Home/lib
it will probably require root permissions to make any changes if
you do find a properties setting to control this. I'd still
suspect there isn't one.
The problem is that it's hard to catch errors in file encoding. For
example, one of our developers was writing strings containing the
copyright symbol. The file encoding was MacRoman, and because she
was on a Mac, the java compiler (correctly) assumed that the file
was MacRoman and generated code that ended up outputting a MacRoman-
encoded copyright symbol. The code ends up outputting a UTF-8
encoded byte stream, and so on her machine the webapp behaved
correctly.
However, building on the linux server, javac interpreted the source
file as UTF-8, and of course the resulting output was incorrect.
Had the Mac been assuming UTF-8 everywhere, this problem would've
been detected very early, and hours of hunting might've been avoided.
If I could set the file encoding system-wide, then javac would also
use the right encoding.
I don't see why Mac OS X still has MacRoman encoding in the jvm...
What other platforms use UTF-8? I thought this tended to be the
preferred latin encoding. Might be wrong.
Someone could still correct me if wrong but I don't think it can be
user changed for all JVM's.
That might also introduce bugs where you develop for one encoding but
all your users have another. Or have strange side effects for other
java applications.
javac -encoding maybe for the build?
