Compiler Error C2002

invalid wide-character constant

Remarks

The multibyte-character constant is not valid.

To fix by checking the following possible causes

1. The wide-character constant contains more bytes than expected.

2. The standard header STDDEF.h is not included.

3. Wide characters cannot be concatenated with ordinary string literals.

4. A wide-character constant must be preceded by the character 'L':

   L'mbconst'
   

5. For Microsoft C++, the text arguments of a preprocessor directive must be ASCII. For example, the directive, #pragma message(L"string"), is not valid.
