If for some reason the above don’t resolve the issue, you may be able to use the command line interface (libreoffice) to convert the .doc file to a .txt file, which may open up other options for copying text out.
e.g. libreoffice --convert-to txt foo.odt
will create foo.txt with a best effort of extracting the text. (Can also be used for doing conversion to PDF for export.)
Notes:
- Not tested on the Librem 5.
- Not testing with
.docbecause I don’t have a file in such an ancient format
handy.
The above command will take a wildcard too, if you have lots of such .doc files.
