At this time, our cards do not support most non-english characters. Some fonts will support certain accented letters (e.g. é, ü, etc.) if they're copied and pasted into the card.
If you need to have another language placed on your card, or are having trouble adding a special character, you can reach out to us and we can help.
In your message, include the card you're working on and any information our team may need to know in order to help finalize your design.
