i'm trying set external ttf , able render image out of pdf containing arabic caracters , font need set "arial" , having done console keeps on informing it's using defaultfont instead of arial.

 org.apache.pdfbox.pdmodel.font.pdsimplefont drawstring attention: changing font on <3> <arial> default font
