Convert char* to wchar* in C

Question

I would like to convert a char* string to a wchar* string in C.

I have found many answers, but most of them are for C++. Could you help me?

Thanks.

Answer 1

setlocale() followed by mbstowcs().

Answer 2

If you happen to have the Windows API availiable, the conversion function MultiByteToWideChar offers some configurable string conversion from different encodings to UTF-16. That might be more appropriate if you don't care too much about portability and don't want to figure out exactly what the implications of different locale settings are to the string converison.

Answer 3

if you currently have ANSI chars. just insert an 0 ('\0') before each char and cast them to wchar_t*.

Answer 4

Try swprintf with the %hs flag.

Example:

wchar_t  ws[100];
swprintf(ws, 100, L"%hs", "ansi string");

Answer 5

what you're looking for is

mbstowcs

works just like the copy function from char* to char*

but in this case you're saving into a wchar_t*
