11:22 PM Ruby Bug #17037: rounding of Rational#to_f

Test case:
```
def test_rational_with_large_integer_components_to_f
r = 450359962737049649/450359962737049600r

08:02 PM Ruby Bug #11183: Cumulative error on Complex::I ** 100000000000000000000000000000000

This behavior still exists in Ruby 3.2.2.
In order to fix this Complex#** would need to handle the special cases of self being 0+1i and 0-1i.
Correct:
```
irb(main):052:0> Complex(0, -1) ** 1000000000000000000

I'm not able to replicate this in Ruby 2.6 or Ruby 3.2. Has this been fixed in the relevant compilers? If so can this bug be closed?

06:46 PM Ruby Bug #7742: System encoding (Windows-1258) is not recognized by Ruby to convert back to UTF-8

If I understand correctly this test case should convert correctly and not raise a Encoding::ConverterNotFoundError error.
```
"\xE3\xEC".force_encoding(Encoding::Windows_1258).encode(Encoding::UTF_8)
```
