Hi,

  Does main function support unicode?
int main( int argc, char** argv ) can I say int mainw( int argc,
wchar_t** argv )?

Thanks

The Standard doesn't have any unicode (or Unicode or UNICODE) support 
AFA main function is concerned, but the implementation (the compiler and 
the library) are allowed to provide whatever other variations of the 
main function they need.  The reason it's not in the Standard is that it 
would make no sense to require 'mainw' function on the systems that have 
no use for Unicode.

With regards to the function signature, no.  Beyond that, any
Unicode support (including in wchar_t) is currently
implementation defined.  The implementations I use allow Unicode
(UTF-8) in the argv strings, but don't require it.  (The real
issue, of course, is where argv comes from.  Unix, for example,
allows everything but a '\0' character in each argv argument,
just copying whatever it is given by the program which invoked
your program.  Windows is a bit more complicated, but I think it
will work the same regardless of whether you pass UTF-8, 8859-1,
or some other ASCII based encoding---I *think* that it only
treats tab (0x09), space (0x20) and quotes (0x22) specially.)
