I'm not aware of any differences between the platforms in this respect. it could be a font issue, but before you start importing Windows TT fonts, try to Merge or Xref the DWG instead of Open. These methods work differently, so it might work. You could also try to just drag-and-drop the DWG into an empty floor plan window, or open it as an object.
If you can't make it work, report it as a bug through your reseller.
