The wallet was already created successfully before this error, but the unhandled exception caused sys.exit(1), breaking automation. Changes: - Add _safe_echo() wrapper that catches UnicodeEncodeError and retries with an ASCII-safe version (e.g. "OK!" instead of "✅") - Add _ascii_version() helper that maps emoji prefixes to ASCII tokens - Separate wallet creation from output in wallet_create() so the creation itself is never affected by encoding errors - Apply _safe_echo to all emoji-containing click.echo() calls across wallet_create, wallet_send, node_status, and attest functions Added test suite covering: - Unit tests for _ascii_version emoji replacement - Integration tests verifying _safe_echo falls back correctly - End-to-end test that wallet_create exits 0 even when emoji fails No changes to clawrtc Python files — they use plain ASCII print() only. --- sdk/python/rustchain_sdk/cli.py | 95 +++++++++--- .../rustchain_sdk/tests/test_cli_unicode.py | 139 ++++++++++++++++++ 2 files changed, 210 insertions(+), 24 deletions(-) create mode 100644 sdk/python/rustchain_sdk/tests/test_cli_unicode.py diff --git a/sdk/python/rustchain_sdk/cli.py b/sdk/python/rustchain_sdk/cli.py index fa40a3dd0..dc99f8ec8 100644 --- a/sdk/python/rustchain_sdk/cli.py +++ b/sdk/python/rustchain_sdk/cli.py @@ -24,6 +24,51 @@ from .exceptions import RustChainError +# --------------------------------------------------------------------------- +# Safe emoji output — falls back to ASCII on encodings that choke on emoji +# (e.g. Windows CP850).
