[Pharo-project] mac-roman encoding borken?

Hi We have some failing tests in Seaside in the latest versions of Pharo that work in older versions. A short analysis seems to indicate that the there are some issues with mac-roman support in current versions Pharo. To be concrete the following code used to work in older versions but fails for newer ones. (('äöü' convertToEncoding: 'mac-roman') convertFromEncoding: 'mac-roman') = 'äöü' Is anybody aware of any changes? Should I open a bug? Cheers Philippe
