While "KBC 18" appears in various file-sharing directories as a downloadable asset, the actual typography used on-screen for KBC 13 (2021) and subsequent seasons is primarily based on Copperplate Gothic.
KBC 18’s use of a normal western font in 2021 wasn't a lack of creativity; it was confidence. The show no longer needs flashy letters to create drama. The drama comes from Mr. Bachchan and the escalating prize money.
Character Mapping: Because these are legacy fonts, they map Hindi characters directly over standard Western (Latin) keyboard layouts. Typing a "Western" character produces a specific Hindi character.
