Hi there, This is great to see some unicode handling in VTK. However looking at the comited code: http://public.kitware.com/cgi-bin/viewcvs.cgi/Utilities/utf8/source/utf8/core.h?r1=1.1&r2=1.1.2.1 I see this: typedef unsigned int uint32_t; Could someone add some tests on 64bits machine :) Thanks, -- Mathieu
