Got it. Thank you.

Misc #19088: Complex() method with `exception: false` option still raises exception when String argument is in non-ASCII-compatible encoding

----------------------------------------
I've noticed a minor inconsistency of the `Complex()` method. When it is called with `exception: false` option I suppose it shouldn't raise any exception.

For instance it doesn't raise error in the following cases:

```ruby
Complex("1+2ifoobar", exception: false) # => nil
Complex("1+2i\0", exception: false) # => nil
```

But it still raises error when argument is in non-ASCII-compatible encoding:

```ruby
Complex("1+2i".encode("UTF-16"), exception: false)
(irb):4:in `Complex': ASCII incompatible encoding: UTF-16 (Encoding::CompatibilityError)
```

I am wondering if `exception: false` is supposed to suppress this exception as well.
