Suggestion: When copying text, replace the line break with a space

[susemercury]

When copying multiple lines of text, a line break is added at the end of each line. This will divide a piece of text into several parts that don't form sentences. I have to replace the line breaks before I can translate it.

There are no text nor line breaks in a PDF just lines of binary input output. SumatraPDF has no command line text export , That is done by Windows. So the breaks are introduced by the "Binary to Text Extraction" thus ask Windows not to add them to the clipboard.

There are Windows clipboard tools for cleaning output or use an App like Acrobat text extraction which is a heavy weight Acrobat Reader add-in like several others.

You can add your own extractor so here I use the Poppler line by line PDFtoTEXT
