Techopedia Explains ANSI Character Set

The ANSI character set was the standard set of characters used in Windows operating systems through Windows 95 and Windows NT, after which Unicode was adopted. ANSI consists of 218 characters, many of which share the same numerical codes as in the ASCII/Unicode formats.

Central to the idea of creating a curated character set is that standards makers need to judge which types of linguistic and international characters should be included in the set. For example, standards committees may judge whether or not a certain character could be effectively rendered by other characters, in which case it may not be included. Creating standardized sets of characters such as an ANSI character set allows for more consistency and efficiency in the delivery of services, cross-platform development, and programming.
