Re: [NTG-context] Font error in PDF using ConTeXt and Kepler typeface

Another check you can do is to run $ mtxrun --script font --list --name '--pattern=*kepler*' and see if the file for keplerstd-light is the one you are expecting and not a second copy somewhere that is upsetting things.

tex/texmf-fonts/fonts/data/lucida

Of course you need to run mtxrun --generate afterwards so that the files can be found.

Hello, Werner: Have you tried some diagnostic tests, such as trying to get the PDF output via DVIPS? I suspect that you are, in fact, more knowledgeable and experience with ConTeXt than I am, but for what it is worth you may want to look at: • \setupoutput[dvips,acrobat] (see: Context-The Manual (Hans Hagen; English, page 24)) • \showbodyfont[Options] (see: Not-so-short Intro to ConTeXt (J. Ataz-Lopez;English, page 114)) • $ mtxrun (mtxrun is the ConTeXt TDS Runner Tool) command from a terminal window it has has a large number of options for finding the fonts installed, and for querying their characteristics (see: Fonts out of ConTeXt (Hans Hagen, pg 52 and ff)) Em

may I ask again. How could I debug the font typesetting of PDF files with conTeXt?

Any help is highly appreciated.

I'd like to use the commercial Adobe Kepler typeface (Kepler Std - version 2.020) in conTeXt (v2023-04-15) as text (serif) font. Although the font files are loaded correctly (see log below), the generated PDF is unreadable (see attached image).

Notes: - Only serif font (keplerstd-light.otf) is not working. It's not embedded in the generated PDF. - italics and bold fonts are embedded and are rendered well - Can't provide font files because Kepler is a commercial typeface

Do you have any ideas how to debug this issue?

Thanks Werner
