I will try them again in the office...actually I need winzip and nero SDKs to support unicode filename...but since the applications support unicode filename, there must be some versions of SDK support it though the ones i am using now do not..
倒! if the application is fully unicode compatible, then there is no need for the OS to support it. of course, the OS needs to provide the correct the fonts.
you can try this and see how winzip busted. Select two characters from different code page, say a Chinese character and a Thai character, include them in a filename and see if the winzip or nero works?
