macOS Urgent: Initialize unicode STL string

[goyalpk]

Hi there,
I have declared unicode STL string like below. How can I initialize this string with hard coded string like wide character string intialization?

typedef std::basic_string<unichar> UnicodeString;

UnicodeString myString = L"SampleApp";

Thanks so much in advance.

You might need to be more specific in regard to your intent. It seems like you're trying to do some C++ shenanigans using NSString's unichar, defined here:
http://developer.apple.com/document...e/NSString.html#//apple_ref/doc/c_ref/unichar

If so, what is so bad about an NSString? If you're writing straight C++, why not wchar_t?

With all of that said, using L'w' isn't going to always give you a 16-bit value that would be the same thing as a unichar. This just seems like a whole lot of trouble. You'd need to create a Character Traits for unichar, then, i guess, initialize using an array of unichars with each character cast to unichar.

Short and long of it: why aren't you using NSString or wchar_t?

Thanks so much for reply. I need to use unichar. wchar_t is 4 bytes on Mac while on Windows it is 2 bytes. All the algorithms were written considering wchar_t is 2 bytes.
Thanks.

Why not use plain std::string with UTF-8 encoding? No incompatibility between Windows and MacOS X, no byte ordering problems.
