Possible encoding problem in loading reports in Pentaho BI #164

Open mysticfall opened 9 years ago

We still need to confirm this, but from the stacktrace below, it seems that it sometimes fails to correctly parse a report file which contains characters with a certain encoding :

I suspect it to be the case that it only happens on a platform where the default encoding is not UTF-8. I'll replace Input/OutputStreams with Reader/Writers for safety and see if it resolves the issue for the original reporter.
