When does this happen?

IF Trace table summary view displays Unicode escape sequences (e.g., \u0421) instead of actual characters for non-ASCII inputs after a recent update that introduced truncation.

How others solved it

THEN In the backend JSON serialization (e.g., `json.dumps`), set `ensure_ascii=False` to preserve Unicode characters. Also review the truncation logic in the summary table rendering to avoid re-encoding or escaping during display.

def _serialize(obj: Any) -> Optional[str]:
    return json.dumps(obj, cls=EventSerializer, ensure_ascii=False) if obj is not None else None
