Muthu Nedumaran has close to 4 decades of experience in designing typefaces for complex scripts. Through his works in fonts and input methods, he revolutionised the Tamil printing landscape in Malaysia and Singapore seeing the migration of all daily newspapers, magazines and books to his digital typefaces.
Muthu has developed numerous typefaces, fonts and input methods over two dozen languages across South Asian and South East Asian scripts. His works are bundled into iOS and macOS and some Android devices and thus used on iPhones, iPads, Android devices and Apple Watches. His fonts and input methods are also used as the standard for Tamil text by the Ministries of Education in Singapore and Malaysia.
