That’s because your data is stored locally, so special characters in the title = special characters in the filename, which isn’t possible. Small but very worthwhile tradeoff.

Sure it is, what is this Windows? Put emojis in your file names, it’s fun.

How is this a small tradeoff? You don't use punctuation signs when writing(even if it's just a title)?

The file title is the file name so what ever's invalid for a file name is invalid as a title.

But there are some work arounds: - Disabling inline title and setting the document title yourself with what ever characters - Using aliases (in the YAML front matter) so you can search a document with it's special character title, and auto-set a link's custom text
