Wide character string class
Author
Hi,
I want to make sure my creations support unicode... imagine it''d sell one day and it doesn''t support wide character strings; that would suck.
I want to use a std::string class supporting Wide character strings.
I got as far as going to www.sgi.com and finding stuff about character_traits and all but all this template stuff confuces me.
My question is: is there a wchar_t string type (basic_string)?
Second, I''d like any pointers anyone can give me about integrating wide char/multi language support with windows apps.
Thanks in advance.

The basic_string class is parameterized by character type, and by that type''s Character Traits. Most of the time, however, there is no need to use the basic_string template directly. The types string and wstring are typedefs for, respectively, basic_string<char> and basic_string<wchar_t>.

I read that part… and missed it
Thank you.
I would still appreciate hints/pointers on wide string issues however.
Under Windows you can compile for MBCS or for UNICODE, and a macro TCHAR will be defined as char or wchar_t respectively.
I typedef std::basic_string<TCHAR> tstring; (along with a huge pile of other typedefs, #defines, and overloads) to have a consistent (portable) syntax for compile the code with both unicode and a multi-byte strings.
The most annoying part, is the unicode string literals needs to be prefixed by L. So you need a marco to decide if you need the prefix or not, I use SC for lack of a better choice.
tchar str[] = SC("This will work with both MBCS and UNICODE");
tcout << str << endl;
size_t n = tcslen(str); //calls strlen for MBCS, wcslen for UNICODE
It's important to remember that the character size can be either 1 or 2.

Would SC (in the Unicode case) be #defined as
#define SC(x) L##x
?
I like this #define and typedef idea.
#define SC(x) L##x
?
I like this #define and typedef idea.

Maybe I''m missing something but why not just use the _T or TEXT macros provided in Windows SDK tchar.h header file?
TCHAR* p = TEXT("My text");
Under MBCS it will compile as:
char* p = "My text";
and under UNICODE it will compile as:
wchar_t* p = L"My text";
Hehe.

Just use the ones provided in the tchar.h header.
Use _T or TEXT, they both do the same thing.
