We're using Google's Noto fonts ( Noto Sans CJK jp and Noto Sans font families) as Custom font with Jasper Reports 6.8.1. We are exporting PDF with embedded fonts in 10 languages (English/Spanish/German/French/Chinese Simplified/Chinese Traditional/Japanese/Korean/Russian/Italian). JasperReports uses iText 2.1.7 jar to create PDFs.
We've found that using Noto Sans CJK jp font JasperReports Engine succesfully creates PDF which shows all characters correctly in all Web Browsers / Document Viewer app etc. However Adobe Acrobat reader is not able to extract embedded fonts and hence doesn't render the localized data/label on PDF.
Tried encoding 'CP1252'/'Identity-H'/'CP1250', however none of this shows the localized data in all the mentioned languages.
Can you please provide any official guideline about handling fonts on Adobe reader for PDF?
