Are all control characters unsafe?
No. Newline and tab are often expected, while unexpected controls in identifiers or payloads are risky.
Unicode Control Characters
Unicode control characters are often invisible and can silently alter parsing, rendering, and data exchange.
Quick checks
- Find C0/C1 controls hidden in copied text.
- Prevent parser and CSV/JSON ingestion issues.
- Review non-printable bytes before storing data.

FAQ
Why do APIs reject seemingly normal text?
Many validators disallow non-printable controls, which can trigger hard-to-debug validation failures.
Should I remove every control character?
Prefer context-based cleanup. Keep expected formatting controls and remove unexpected ones.
