Thank you all for your reply! @PMario <[email protected]> I actually want to use the filter in real cases! Text is created in Tiddlywiki itself or important from the net. For example Fortran code downloaded from the net and imported into the wiki! Most of these I think were created in the Unix system! So I like to make sure the filter works in all cases.
@Jean-Pierre Thank for the suggestion! I will test it! I do not have a Mac computer but I think I should download text files created in Mac or use Notepad++ to use such newline chars.
