Re: [xmlvm-users] support of unicode String

[Panayotis K. <pan...@pa...>]

After some thoughts I believe there is a more appropriate solution.
Java's "char" is actually a "unichar" and I think it should be handled like
this most of the time.
Which actually is a synonym for "unsigned short".
Thus the produced table is not "wrong", it's just the wrong type.


Under ObjC is more like a chaos, I tried to correct some parts (and I am
surprised that it didn't break many things, but now I understand why quite
often the unicode characters were not properly supported. I tried to
correct some.

PS, I have written some code to deal with varargs, which is really a pain.
The code is under xmlvm.m in ObjC. Just in case you need it, it is there.
