At present (12/2010) the JobScheduler is able to accept all Unicode characters in the scheduler log.
E.g, if your script or program, executed under control of JobScheduler, put some Unicode-characters to stdout or stderr, this will be shown correctly.
All other text,
- error-, warning and info messages,
- GUI-text,
- log-file entries,
- help- and tooltip-texts
- ...
are in English and German only.
One major topic on the road-map of JobScheduler is the translation (i18n = internationalization) of all texts.
JOE (the JobScheduler Object Editor), which is used to create the xml-configuration for JS Objects, will create the xml-files with an encoding of ISO-8859-1. To use Unicode, one has to change this encoding to "utf-8" (or something like that).
