Lỗi phông chữ khi gõ tiếng Việt có dấu thường do chưa chọn đúng kiểu gõ hoặc font chưa hỗ trợ Unicode. Bạn thử kiểm tra lại bộ gõ (như Unikey), chọn kiểu Unicode và font chữ như Arial, Times New Roman để xem có khắc phục được không nhé!

Another workaround you could try: if the font you're using doesn’t support “ß” (Eszett), you could manually create it by combining characters, especially if you're only using it for titles and not for body text.

For example, you might try overlapping or slightly adjusting:

A stylized “B”, slightly modified to look closer to an “ß”

Or take the lowercase “s” + “z” from the same font, place them close together, and convert to outlines in your design software (like Illustrator or InDesign). Then adjust the shapes manually to mimic a proper ß.

Also worth checking: you could ask the Cupid de Locke font creator (via DaFont or wherever you downloaded it) if they have any updates or alternates — sometimes designers can share a custom glyph or suggest something compatible.
