I suspect that as the Arialuni.ttf is 20MB it is taking some overhead on the rendering and causing failures. is there a way to optimize this approach? here is our properties file which we use to embed the TTF: Arial=arialuni.ttf Serif=arialuni.ttf Times New Roman=arialuni.ttf SimSun=arialuni.ttf Any advise would be much appreciated PD4ML July 24, 2017 at 17:01 #30060 Take a look to the TTF fallback tables on the page: http://pd4ml.com/cookbook/pd4ml_pdf_true_type_fonts.htm In principle you may use the font names (ignoring their original meanings) to define a chain of CJK TTF fonts, to be used to find a particular glyph, missing in the main font: [language=java:1nn401ks]MS Gothic=cjk_font_option1.ttf MingLiU=cjk_font_option2.ttf SimSun=cjk_font_option3.ttf Mangal=cjk_font_option4.ttf David=cjk_font_option5.ttf Gulim=cjk_font_option6.ttf [/language:1nn401ks] Author Posts Viewing 2 posts - 1 through 2 (of 2 total) The forum ‘HTML/CSS rendering issues’ is closed to new topics and replies.
