Font problem in pdf

[Wrumm]

Hi,

I have two PCs that are more or less installed similarly.
If I open certain PDF files with Sumatra from my bank on PC A, everything looks fine. If I open the same files on PC B with Sumatra, some of the text is unreadable because the letters are replaced by strange symbols.
If I open the files with Acrobat Reader on both PCs they are displayed correctly.

So there must be something wrong in the configuration of PC B that is only effecting Sumatra to display the files/font correctly. Re-installation of Sumatra didn't help and I do not see at least any obvious difference in the Windows Fonts between the two PCs.

Where do I start to investigate the issue?

A properly generated PDF should include the font data for non-standard fonts.

Incorrectly generated PDF refer to non-standard fonts only by name. In that case Sumatra tries it's best to find a matching font in Windows.

That might fail, especially for chinese/japanese fonts.

You can see a list of fonts in a PDF using pre-release SumatraPDF (https://www.sumatrapdfreader.org/prerelease), opening PDF and pressing Ctrl-D and then "Get Fonts Info" button.

That will give you list of fonts.

I need to add a way to view internal Sumatra log as that logs info if the PDF file is not correctly generated.

I had the same problem on some of my files using SumatraPDF 3.3.3-64 bit.
I downloaded and built the current version on GitHub (3.4) and the problem does not seem to exist anymore - the files are now again shown as expected.

Yes, it's possible that some improvements since latest released version 3.3.3 improved font matching.

With bugs it's always recommended to test with pre-release version https://www.sumatrapdfreader.org/prerelease

Thank you for the advice.
I used today's prerelease version v3.4.14378 as 64-bit and portable version and with that the pdfs are displayed correctly on PC B.
That is great :-), but I still do not see the reason for the problem before. I do not see any obvious difference in the mentions fonts for the two PCs. On both I have no "Helvetica" but a "Helvetica Fett" (fett = bold in German) and I have "Courier New" with the four subtypes "standard, bold, italic, bold-italic" (already translated) and a single Font "Courier Standard". But all on both PCs the same.

The fonts in the files are:
Courier (Type1)
Courier-Bold (Type1)
Helvetica (Type1)
Helvetica-Bold (Type1)

Not sure if it makes sense to investigate this more, since it is working with the prerelease. Any plans when this will be released?

I don't know when the next release will be.

Pre-release is more than good enough for daily use. Unless you get a bug that affects you frequently in which case you can open a bug and hopefully I'll fix it promptly.

Thanks for the help!
