In a heterogeneous environment, Adaptive Server may need to communicate with clients running on different platforms using different character sets. Although different character sets may support the same language group (for example, ISO 8858-1 and CP 850 support the group 1 languages), they may encode the same characters differently. For example, in ISO 8859-1, the character à is encoded as 0xE0 in hexadecimal. However, in CP 850 the same character is encoded as 0x85 in hexadecimal.
To maintain data integrity between your clients and servers, data must be converted between the character sets. The goal is to ensure that an “a” remains an “a” even when crossing between machine and character set boundaries. This process is known as character set conversion.
