Remove disallowed filename characters from title

[deathau]

As mentioned on the Obsidian Forum

It's already stripping out explicitly disallowed characters in filenames (\/:*?"<>| and \u00A0) but for saving files for use in Obsidian, [] should also be disallowed (due to linking syntax).
They are valid file name characters though 🤔
Perhaps an option to add additional disallowed characters? with [] set by default?

Hashes, too (#) — could mess up links in Obsidian
Names starting with ^ could be an issue with footnotes as well.
