UTF-8 is entirely different than Ascii, and extended Ascii with code pages. The UTF-8 values from x’00’ to x’7F’ are the same as the Ascii characters. Values from x’80’ and above use a special encoding to represent up to 4 byte UNICODE characters. A single 4 byte UNICODE character can require 6 UTF-8 bytes. Easytrieve doesn’t support UTF-8 encodings that are not Ascii characters on any platform.
Additional info; The UTF-8 support may be added as a enhancement function with a enhancement request from Japan. (Dec 22, 2018.)
