Under start.bat the server's stdout/stderr are pipes into PowerShell's Tee-Object, so Python encodes with the ANSI code page instead of the wide console API. cp1251 (Russian Windows) cannot encode the banner's box-drawing rule (U+2500), and that print killed the server with UnicodeEncodeError before it could listen. - _guard_console_streams() (the first statement of main()) sets errors="replace" on both streams: an unencodable character prints as '?' and can never raise. - _console_rule() picks the widest banner rule its stream can encode - U+2500 where the code page has it (utf-8, cp437), ASCII dashes otherwise (cp1251, ascii). - The seven text-layer trace strings are ASCII now: the APDU arrows (U+2192) and the INIT/CAP-COMPAT em dashes (U+2014 - cp437 cannot encode them either), so the traces stay readable on any code page. The raw os.write paths (_log_stdout, the APDU tracer) bypass the text layer, cannot crash, and were left as-is. Tests: tests/test_console_encoding.py - the strict-cp1251 control, the rule's fallback/pretty cases, the guarded banner+traces, a stream without reconfigure, the main() source pin, and an AST pin that no print/stdout/stderr literal in the package is non-ASCII. tests/test_startup_cardless.py's CARDLESS_LINE follows the new ASCII line. Verified with PYTHONUNBUFFERED=1 PYTHONIOENCODING=cp1251: the pre-fix code died at the banner, the fixed code reaches the listening banner and serves a command (CMD: -> OK, no encode errors). 930 frontend + 952 Python; sw cache simple-v453.
