create a jar file with a package that has multibyte
in it's name and go thru the wizard to the generate manifest information
pane. 
The multibyte is not shown correctly.

Also, from the jar properties window, the manifest entry - the
manifest window again does not show multibye correctly.

Also
in a pseudo localized FFJ, on the Choose contents for jar file
panel of the wizard, the directory prefix window is partially covered
by the source/destination/file filter column headings without needing
to resize greatly ,and sometimes the file tree under Source:
gets compressed upon resizing, sometimes not, but this appears random -
in general, user of a localized product should not need to resize
window if user of English product does not.
