PDF is not readable
PDFs generated from our browserbased office management software are not readable with older Acrobat Versions on Mac (OSX 10.11.6, Acrobat X 10.1.16).
All used fonts are embedded but the letters are disarranged. See example below. With the default PDF reader for Mac "Preview" everything is fine. Thank you for your help.
