UTF-8 vs UTF-16 encoding confusion Playbook
UTF-8 vs UTF-16 encoding confusion. Actionable remediation checklist with tool links and relevant guides.
TL;DR: Validate -> locate exact failing spot -> fix the minimal part -> re-validate.
Execution steps
- Validate input locally. Start with a validator or parser-friendly converter.
- Locate root cause. Use line/position/error token to isolate one failing place.
- Apply a minimal fix. Do not refactor all content at once.
- Re-validate and continue. Once clean, convert/export safely.
