For label and button objects, only one font can be specified for each. However, it brings me a problem a bit for Japanese environment.
In fact in my Japanese pages that are very font design concious, I need to specify multiple fonts to avoid "garbage-text" problem between Win and Mac. This is because the available font set and font substitute rule are very different between Win/Mac. Actually CSS's font definitions for my page has to specify Osaka,Verdana,'MS UI Gothic' in this order. This technic does solve my problem but the only point is that Dynamic HTML Editor does not allow to assign multiple fonts to an object in its GUI design, so I have to patch the generated HTML by hands.
Doesn't the next version support multiple font assignment?
