I found japanese fonts are not applied on thumnails.
I found PortionFormat.EastAsianFont is null.
I tried this:
if (portion.PortionFormat.EastAsianFont == null)
{
portion.PortionFormat.EastAsianFont = new FontData("+mj-ea");
}
Then correct fonts are applied on thumnails.
I found when PortionFormat.EastAsianFont is not null, fonts are applied on thumnails.
If I can know the correct font in portion is "+mj-ea" or "+mn-ea", I will resolve this probrem. But I can't find the way.
What would be the best way to do this?
Thank you in advance.
