Hello,
Thank you for your update. Since the issue with emojis displaying as question marks persists even when using default WordPress themes and with most plugins deactivated, this indicates that the problem is not related to the WoodMart theme.
This is likely due to your website’s database character set or server configuration not supporting emoji characters properly. We recommend checking that your database tables use the utf8mb4 character set and collation, as this is required for full emoji support. Additionally, please ensure your server and WordPress installation are configured to handle utf8mb4 encoding.
You may want to consult with your hosting provider or a developer to adjust these settings accordingly.
Regards
