Guvnor and Designer are already internationalized with UTF-8 encoding. If JVM is running under encoding other than UTF-8, it might hit unxpected issues. So please add a note to run JVM under UTF-8 (with LANG or JVM option '-Dfile.encoding=UTF-8').
I've added the following content to the Customization chapter, just after the language settings section: JBoss Enterprise BRMS is designed to work with UTF-8 encoding. If a different encoding system is being used by the JVM, unexpected errors might occur. To ensure UTF-8 is used by the JVM, use the JVM option "-Dfile.encoding=UTF-8". As soon as it is live on the internal doc stage I will provide a link and update the status to ON_QA - Lee
Confirmed that the note is there.
