Losing german äüö (Umlauts) and letters in the Structure Tree when using "Add Tags to Document" in Adobe Acrobat DC
- Brief Title
Losing german äüö (Umlauts) and letters in the Structure Tree when using "Add Tags to Document" in Adobe Acrobat DC (previous operation Number ADB-3207012-T1M7) German Language Problem?
- Steps to reproduce the issue
Export a text document with german words that contain german umlauts (äöü), e.G.: "für, können, öfter, mögen" as a PDF without tags from InDesign or Word
Open the file in Acrobat DC
Go to "Tags" and open the little menu and choose "Add Tags to Document"
After the Structure Tree was created — save and close
when you open the document again in Acrobat DC and you can take a look at the tags in the Structure Tree and see that the letters are missing in the tags. Not only the umlauts but sometimes accompanying letters aswell
Examples: "für" -> "fr"; "können" -> "knen"
Conclusion: blind people can't read these anymore and the document is not accessible anymore!
The problem doesn't exist in Acrobat X and Acrobat XI.
The problem occurs with any font and all operating systems.
The problem was already documented with video and example-documents with the operation Number ADB-3207012-T1M7.
- Operating system

- Expected results
Loss free texts in the Structure Tree with umlauts and all other letters so that the docment can be read by screen-readers.

Color chip flooring, also known as flake flooring, is a decorative and durable surface often used in garages, basements, and commercial spaces. It consists of colored vinyl chips embedded in a resin base, usually epoxy or polyaspartic. These chips add texture, color, and slip resistance to the floor. The result is a seamless, easy-to-clean surface with a speckled appearance. Color chip flooring is popular for its customizable look and high-performance finish.

Hello, I know this really „annoying“ problem als well. Creating Accessible PDF files is getting more and more important in these times and especially for my clients in the social area. I usually use Acrobat CC since a few years (meanwhile on macOS Big Sur 11.2.1.), but fortunately I didn’t scrap my old iMac, so that I can still use my old Acrobat 9 (!!!) for the first step to create a structure tree. Otherwise I also have the problem with german umlauts »öäü«. I can see in this forum, that Adobe knows this problem since at least 2018.
Looking forward for a solution, that’s – sorry for these clear words – kind of embarrassing!!!

Hello Team,
I told you in 2018 about the problem with the Umlauts in the stukture-tree and nothing happen till now! Last week I had a adobe acrobat dc release 2021.001.20138, but the mistake is still there.
Please take it serious! My colleagues and me cannot update our Mac to Big Sur, because you no longer support Adobe Acrobat XI. Or we had switch between the platforms, where the Adobe Acrobat XI can runs. You can't work like that!
Thank you in advance.

I can confirm the issue from MS Word. French glyphs éàè work, even arabic does. But no Umlaut.
The issue does not occur when the document was created by LuaLaTeX.
In pdfLaTeX documents äöü are converted to ŁoŁ in the tag tree. In reflow view you get ¨a etc.

Hi Rachid,
we still waiting for the release!
It is incredibly important, because the new macOS Catalina don't support the Acrobat X and XI.
What should we do?Best Regards
Nicole

Hello, I work for the german Radio/tv Station (Deutsche Welle), that Nicole mensioned in her comments. As long as the problem is not fixed, we are not able to produce accessible pdf documents using Accrobat.

Hello Team, I still waiting for a feedback of you. Can you tell me, how it continues? This problem is very urgent. Two weeks ago, I gave a workshop about accessibility at a german television and radio institution »Deutsche Welle« and they have the problem, too. The biggest problem is, that the acrobat XI license ends and they had to use acrobat DC now. And now they are unable to generate the structure tree automatically without losing the german umlauts. Alle the documents are unusable!!! (They work with microsoft) Thank you for a fast response.

Hello Team, the exact thing is also happening with my Acrobat DC on OSX 10.13.6

Good morning,
yes, I can confirm that it is mostly on all files with german umlauts »öäü«. But the problem don´t exist, when you create the file with acrobat.
We have the problem on different OSX and Windows Versions.I create a textfile in InDesign with words like »für, können, ähnlich« etc. an export a PDF without tags.
Now I open the PDF file in Acrobat DC and create a structure tree with the function »add tags to document«.
when I open the structure tree and look at the text-fragments in the tags, you can see that »für« becomes »fr«.
Sometimes this phenomenon occurs after saving this file.It`s a shame, because we don´t have the problem with acrobat X and XI!
I send you a PDF with this problem enclosed. Please delete in that file the structure tree and create a new one with »add tags to document«.
Or is it possible to send you a screen recording? It is a big problem for our accessibility work!I currently working with mac OS high sierra 10.13.6
Thank you!
