How to Diagnose an API Integration That Rejects Valid Unicode Text

11/11/2026

An integration may reject names or content containing accented characters, non-Latin scripts, or emoji because of encoding assumptions, database collation, validation rules, or byte-length limits.

What to check

Capture a sanitized failing example, compare request encoding and response details, inspect validation and database character set, and distinguish character count from encoded byte length. Test several scripts safely.

Recommended next step

Use consistent Unicode handling end to end, set appropriate field limits, and preserve original text without lossy conversion. Add international test cases and verify downstream display and search.
