```cpp
void f(char8_t c8, char16_t c16, wchar_t cw) {
bool a = c8 == c16;
bool b = c8 == cw;
}
```
Currently, only the first line raises `-Wcharacter-conversion`; the second line doesn't.
However, a comparison between `char8_t` and `wchar_t` is just as nonsensical as a comparison between `char8_t` and `char16_t`, so this seems like a false negative. That is especially true when considering that `wchar_t` is often UTF-16 or UTF-32, depending on the platform.
