Compiler Error C3851

'char': a universal-character-name cannot designate a character in the basic character set

Remarks

In code compiled as C++, you cannot use a universal character name that represents a character in the basic source character set outside of a string or character literal. For more information, see Character Sets. In code compiled as C, you cannot use a universal character name for characters in the range 0x20-0x7f, inclusive, except for 0x24 ('$'), 0x40 ('@'), or 0x60 ('`').

Example

The following samples generate C3851, and show how to fix it:

// C3851.cpp
int main()
{
   int test1_\u0041 = 0;   // C3851, \u0041 = 'A' in basic character set
   int test2_A = 0;        // OK
}
