LibreOffice headless pdf conversion different word breaks – how to equalize? [closed]

by

When I convert a docx document to a pdf document at my development computer (debian 12.2 with LibreOffice 7.6.3.2), then the pdf document contains hyphenation: a long word is split up into two lines, e.g. the German word “Datenschutz” is split up into “Daten-” at the end of one line and “schutz” at the beginning of the following line.

When I convert the same document to a pdf document at my server (debian 12.2 with LibreOffice 7.6.3.2), then the pdf document contains no hyphenation. “Datenschutz” is moved as a hole into the second line and this happens also with all other long words at the end of a line. They are not split up.

In both cases I use the same command:

libreoffice7.6 --headless --norestore --nofirststartwizard "-env:UserInstallation=file:///tmp/LibreOffice_Conversion_myuser" --convert-to pdf:writer_pdf_Export --outdir /home/myuser/ /home/myuser/test.docx

Where could this difference come from?
And how can I equalize the output so that both systems split up / break words?

In both cases the font is Verdana and in both cases I installed ttf-mscorefonts-installer 3.8.1. So the size of the characters should be the same in both cases.

    Format/Paragraph uncheck 'Automatically', then words should not get breaks. (found here: ask.libreoffice.org/t/… )

  • Nice. This equalizes the results. Unfortunately there are a lot of very long words in the documents so I would prefer to do “always on” instead of “always off”. But turning hyphenation off is a (temporary) workaround. 🙂 Thanks!

    You can change when words get hyphenated by changing the options, one of them can only hyphenate long words, if set to a high enough value (see: Minimum word length in characters

  • I’m voting to close this question because changes of getting an answer about programming is not likely…. 😉

After installing the German language pack hyphenation is equal in both cases.
