This adjusts the Windows console to switch the codepage to UTF-8. This is important as the default codepage (CP437) does not allow for UTF-8 output, but expects ASCII. However, strings in Swift are assumed to be UTF-8, which means that there is now a conversion mismatch. Because the console mode persists beyond the duration of the application as it is state local to the console and not the C runtime, we should restore the state of the console before termination. We do this by registering a termination handler via `atexit`. This means that an abnormal termination (e.g. via `fatalError`) will irrevocably alter the state of the console (interestingly enough, `chcp` will still report the original console codepage even though the console will internally be set to UTF-8). Fixes: SR-13807 (cherry picked from commit 9847cab)
Enable the test that was previously failing on 5.5. This has been stable on main for a while, and seems to also be now passing on 5.5
