[Pharo-users] Dues anybody try Artifact with non latin characters?

Hi. I need to generate PDF with russian letters but when I try it resulting pdf is empty. I use example: oneLineTest: aStream PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello Привет'; from: 10mm@10mm)); exportTo: aStream. I attach produced pdf. Best regards, Denis
