Okay I may end up eating my words on this one.

I can't reproduce on VS 2022.

But what I can get on dmd&ldc rather than VC is:

```
   Creating library test.lib and object test.exp
test.exp : error LNK2001: unresolved external symbol _µ
  Hint on symbols that are defined and could potentially match:
    _µ
test.exe : fatal error LNK1120: 1 unresolved externals
```

So something isn't right, will need to review this at some other point in time
and file a different bug report if I can figure out what is going on there.
