Poppins not Working as Custom Font for PDF Generation - Roboto works as expected. Why?!

[oruehenbeck]

• Have you consulted the documentation? Followed the documentation to the letter. Tried multiple variants just to be sure. Tried other fonts, Problem only occurs as soon as soon as I use any of the poppins ttf files.
• Have you googled your question? Yes I have, found no related issues.
• Have you asked your colleagues for help? No colleagues unfortunately. ;)

If you could answer all this questions with yes, please feel free to open an issue with your question. We will try our best to help you.

Added the font, Poppins.ttf is Poppins-Regular.ttf renamed:

        fonts {
            addTTFFont {
                poppins {
                    path = EXT:xxx/Resources/Private/Fonts/Poppins.ttf
                }
                roboto {
                    path = EXT:pdfviewhelpers/Resources/Public/Examples/FullFeatureShowCase/Roboto.ttf
                }
                robotob {
                    path = EXT:xxx/Resources/Private/Fonts/RobotoBold.ttf
                }
            }
        }

If I set "poppins" here, there are letters in the pdf, but they are not visible:

    generalText {
        trim = 1
        removeDoubleWhitespace = 1
        color = #000
        fontFamily = roboto
        fontSize = 8
        fontStyle = regular
    }

Files:

Poppins.zip

Results in the same PDF but not letters are visible. (But I can mark them, so clearly something is happening)

@oruehenbeck I had a brief look at the issue, unfortunately I have not found a solution yet. It looks like a conversion issue in the TCPDF library. I would recommend to look for a solution for similar problems related to TCPDF, e.g. in the GitHub repository: https://github.com/tecnickcom/TCPDF/issues Maybe you could also try to convert the font to a different font format and back to TTF and try it with this new file.
