Description Louis Moureaux 2018-06-10 09:58:01 UTC

When opening a file containing U+2028 LINE SEPARATOR and saving it under another name, Kate turns each line separator into two plain ASCII newlines, even if the document wasn't modified.

This is especially problematic with version control systems, see eg https://github.com/cms-gem-daq-project/gem-plotting-tools/pull/109#pullrequestreview-126431811

Thank you for maintaining such a great editor!

Thanks for the added information. Can confirm after saving the file is different.

I checked that and yes we convert that, like we convert other mixed line endings into the current 'normal one', too.
I don't see that we want to change that, writing out files with mixed line endings is close to never a good idea.
If one wants that, this is a new feature somebody will need to contribute, see https://kate-editor.org/post/2020/2020-07-18-contributing-via-gitlab-merge-requests/
