    Code:
```cpp
const char BUFFER[] = "a\0b";
```
Using `clang_Cursor_Evaluate` + `clang_EvalResult_getAsStr` at least, there's no way to get the full literal.

Doing some debugging I found [this strncpy](https://github.com/llvm/llvm-project/blob/main/clang/tools/libclang/CIndex.cpp#L4384) which doesn't copy anything after the first \0, stripping the actual literal.

Even more, the `clang_EvalResult_getAsStr` only returns a `const char*` and no size, relying on the \0 to get the size of the string.

Is there any other way to get the actual literal? Is adding a new function that can do this something acceptable?
