Sevilla 16 includes a few important changes. Users switching to Sevilla 16 from a previous version should pay attention to this.
Sevilla 16 is primarily based on Unicode where previous versions were based on older character encodings like ANSI. This allows for exiting new functions, like the much easier availability of East-European languages, and not Latin based languages like Greek, Russian, Arab, Hebrew, Thai, etc. In addition, languages that were not supported at all can now be nicely supported. These languages include Japanese, Chinese and Korean. Unicode is widely used on the web, and generally available in modern operating systems.
However, older operating systems do not properly support the many characters of Unicode. Therefore Sevilla 16 will not run on Windows 95, Windows 98 and Windows ME. Probably it will not run on Windows NT and Windows 2000 either. The minimum and recommended Windows version is Windows XP or Windows 2003, while of course all newer Windows versions are supported.
There also are some consequences for data files. When using Sevilla 16 these will by default be written in a Unicode based format (UTF-8). When trying to read these into previous versions of Sevilla this may cause problems. So be careful taking backups if you are switching to the new version. Also language files may constitute some problems. If UTF-8 based language files are used with Sevilla 16 and the system is later downgraded to 15.2- then translation files may cause problems. The installation of older language files may become necessary again.
We believe that these drawbacks are acceptable and necessary in order to keep up with modern developments. Sevilla tries to handle as much as possible any problem that may arise from the encoding change.
