Wrong requests to LanguageTool with numbers and dates.

[Niklas123Niklas]

Hi there,
I am working with TeXstudio and LanguageTool server 6.2 (not the newly developed software, but the old opensource version still available). I encountered a problem in the request sent to the LanguageTool server handling numbers and dates. It seems that numbers are ignored and not sent to the server for spellchecking, leading to false error messages when writing a date like 11.10.2023. Instead of the date, only two dots are sent and result in an double punctuation error. This also leads to a case error for the following word. I assume the numbers are filtered. Is it possible to remove the filtering? Or would this create more errors than it solves when processing other text/number combinations?

Environment

• TeXstudio: 4.6.3
• Qt: 6.5.2
• OS: Windows 11
• TeX distribution: texlive

Expected behavior

Send the complete sentence including numbers to languagetool and don´t show errors for double punctuation and case at the beginnig of a sentence.

Actual behavior

Errors for double punctiuation and case at the beginning of a sentence.
I checked the packages sent from TeXstudio to Languagetool using wireshark, if this helps:

How to reproduce

Install languagetool 6.2 from https://dev.languagetool.org/http-server.html
start it with java -cp languagetool-server.jar org.languagetool.server.HTTPServer --port 8081 --allow-origin
Test a sentence in german with a date in it, like Dies ist ein Text der das Datum 10.12.2023 enthält und fälschlicherweise Fehler anzeigt.
