DCI TML Ismail is a popular Tamil legacy font. Unlike Unicode (which is the modern standard for typing Tamil across all devices and platforms), Ismail follows a specific character mapping. This means that if you type in a standard Unicode keyboard, the characters will not match the Ismail font layout.
This font is widely used in traditional printing presses, specific government office documents, and by users who prefer the classic "typewriter" style aesthetic of the script. dci tml ismail tamil font keyboard download
