ANSI vs. Unicode: Know the Difference
By Shumaila Saeed || Published on January 1, 2024
ANSI is a character encoding standard mainly used for representing English, while Unicode is a universal character set supporting multiple languages and scripts.
Key Differences
ANSI (American National Standards Institute) encoding is a collection of character sets like Windows-1252, used primarily for English and Western European languages. In contrast, Unicode is a comprehensive character set that includes characters, symbols, and emojis from various languages and scripts around the world.

While ANSI encodings are limited in scope and can represent a maximum of 256 characters, Unicode has a much larger capacity, being able to encode over a million characters. This makes Unicode suitable for a global audience.

Unicode supports complex text rendering required for languages like Arabic and Devanagari, which ANSI cannot handle. Conversely, ANSI’s simplicity makes it suitable for applications where only English or Western European languages are used.
