Add examples/python/_shared/console.py with safe_print/icon helpers that degrade emoji to ASCII on legacy Windows code pages (cp1252) instead of crashing, mirroring the CLI _supports_unicode/_icon pattern. Wire the helper into the high-severity gateway (16, 17, 18) and channel (20-23) examples so they start on default Windows PowerShell without PYTHONUTF8.

"""Cross-platform console output for examples.
|
|
|
|
Legacy Windows consoles default stdout to a non-UTF code page (cp1252/cp437)
|
|
that cannot encode emoji such as U+1F680. Calling ``print`` with those
|
|
characters raises ``UnicodeEncodeError`` and crashes the example before the
|
|
server starts. These helpers mirror the ``_supports_unicode``/``_icon`` pattern
|
|
in ``praisonaiui.cli`` so examples degrade to ASCII instead of crashing while
|
|
preserving emoji on UTF-aware terminals.
|
|
|
|
Usage:
|
|
from _shared.console import safe_print, icon
|
|
|
|
safe_print(f"{icon('🚀', '[START]')} Starting gateway...")
