What is failing
When I try connecting to a non-exist server, I saw some bizarre error messages.

Expected output
The localized message are shown properly, or just show English ones.

Actual output
The localized message are shown as octal representations.

ssh: Could not resolve hostname nanopim4: \262\273\326\252\265\300\325\342\321\371\265\304\326\367\273\372\241\243

Start by reproducing the hostname-resolution failure described in the report on Windows 10 and review the linked troubleshooting guidance. Trace how the localized socket error is formatted in Win32-OpenSSH; done means the error appears as readable localized text or English rather than octal representations.
