I am using Acrobat Reader v2023.006.20320 on Mac osX Sonoma 14.0, M1 chip.
When reading papers, I copy texts and put them in Google Translate at times. However, Acrobat Reader always maintains the visible "line breaks" at copying, which makes the translation unable to work well, for Google Translate would treat each line as independent sentence, which makes sense I'm afraid.
I would prefer the Preview app's bahivor, which ignores the "line breaks" only for reading. This makes sense, in my opinion, for the line breaks are caused by the limitation of width, not the author's intention.
