It seems that landing page templates don't allow entry of Japanese fonts/text. After typing a Japanese phrase into a template heading and then saving it, it doesn't appear in the preview. Then, after leaving the preview, the text in the heading has disappeared. I can copy/paste Japanese from an external document into the landing page template, but then the heading formatting is lost. Besides that, copying and pasting every line of text from an external document seems kind of ridiculous. There must be a solution or workaround for this. Mailchimp doesn't have this issue at all. This is a deal-breaker.
