Hi team,
I’m hosting my MySQL database and backend on Railway, and recently I noticed that Vietnamese text fields (UTF-8) display incorrectly in the Railway SQL UI.
Example:
Instead of showing
Cải bó xôi hữu cơ
the UI shows
C?i b� x�i h?u c?

However:

• When I connect to the same database through my backend or external MySQL clients (e.g., MySQL Workbench, Python scripts), the text displays correctly.

• Editing data directly in the Railway SQL UI causes double-encoding, making the data permanently corrupted (characters get saved as mojibake).

• My tables and connection are already using utf8mb4 with proper collations.
  It seems the issue is with how the Railway web SQL viewer handles character encoding (not rendering utf8mb4 properly, especially for Vietnamese or other non-Latin text).
  Could you please confirm if this is a known issue with the Railway SQL UI or if there’s a workaround (e.g., forcing UTF-8 rendering or disabling inline edits)?

Thank you! 🙏
