It seems character encodings in requests/responses of BlogJet is UTF-8 and it might be ok even if they include Japanese characters.
But the case when the new entry had linfeeds and Japanese characters, following error was occured.
Entries which has no linefeed could be published. (of course there was no problem without Japanese characters.)
Another case: category labels which had Japanese characters were corrupted. (see below)
In "Recent Posts" window, Sometimes entry title was corruped too, and due to problem, it seems not to be able to retrieve content body.
BlogJet has pretty good interfaces and we hope it could handle mutibyte Japanese characters. Any plans to support them? :)
