To add special characters, you can type the word in a word processor or any text editor where you can add different letters with accents, and then copy and paste this into the text editor on our website. However, check after saving the text as seen in the card preview. If you see a rectangular shape then it means that the font does not support that character and it will print as a rectangle. You can try changing the font style, but if this doesn't work, you can't print the character.
