Japanese and other extended alphabets are working pretty well with NS Basic/App Studio now, with one exception: the characters show up on the Design Screen as rectangles. It’s because the Design Screen does not know what font to use.
The solution is to specify the font in the style property of the
control. Put this string into the style property:
font-family: 'MS UI Gothic';
and it will display properly. For other languages, you will need to change the font name to something that is appropriate.
