I'm convinced we will need to be careful with symbolic links related to new line characters in filenames, but I'm curious of which specific aspect you had in mind.
Oh, nothing specific to newlines. Just, when you rename files to fix newlines, you need to check if they break symlinks pointing to them.
For instance, I had project folders for my individual research projects. In order to have a central repository of resources and not have copies of multi-megabyte pdfs in each folder, I put all referenced papers in a single directory and symlinked them for each project that needed them. Later, I wanted to rename the papers to remove newlines. The symlinks complicated this process quite a bit!
