RH 8, WinHelp, Japanese

Hi. My company recently decided to localize in French and Japanese. Currently we generate WinHelp 2000 using x5. Their plan was to send the raw Word documents to a language translation company and then we would create the WinHelp 2000 project to generate .hlp/.cnt files.

I see that Japanese is not supported in x5, so I'm looking into version 8. But...is WinHelp 2000 a valid output in v8?

(I know we should update our help system to something a little more modern, but that is what the powers that be want for now.)

Thanks!
