No, unfortunately no error messages are showed.
To embed the font I'm just using this code
ALight = Catalogo.AddFont( Server.MapPath("static\font\ARIALUNI.TTF") )
and I'm using this
Set txa = MyGroup.AddTextArea (text, 0, 0, 5, 10, DPDF_Align_Left, ALight, fontSizeValue, Catalogo.Colors.GetCmykColor(0,0,0,1) )
to add it to the PDF.
After the AddFont code, if I use
Response.Write(ALight)
the system print 23, the font value for the last of your chinese embedded fonts.
Thanks for your help,
Simone
