Hello,
I’ve checked your product page, and the unusual characters are appearing due to the Cormorant font family currently being used on your site.
This issue often occurs when the selected font doesn’t support certain special characters or accents used in your text.
To fix this, I recommend switching to a font that fully supports your language’s character set (for example, Roboto, Lato, or Open Sans). You can change this in Theme Settings > Typography and then clear your cache to see the update.
If you have any questions, feel free to contact us.
Best Regards,
