Summary: wide string parsing error

Initial Comment:
Interface file include the header file.

The following example:

== test.i ==
%module test
%{
#include "test.h"
%}

%include "test.h"


== test.h ==
void foo(const char* str);	// OK
void foo(const char* str = "test");	// OK
void foo(const wchar_t* str);	// OK
void foo(const wchar_t* str = L"test");	//error

A fourth of the only makes an error when parsing.

I think it should be possible to parse.

thanks.

Message:
Yes, this is standard ISO C and C++.

For C++, "hod139" quotes the relevant section (2.13.4) here:

I don't have my C standard here, and have failed to track down a quotation
for this online, but I'm certain it's in there too.

Setting category to "parsing" not "code generation (general)"...

Is this in one of the C or C++ standards, and if so which section?

Message:
This is a limitation of SWIG's parser (it doesn't understand wide
strings).

A workaround is to add "#define L" near the top of your interface file
(.i).
