Currently, when you create or rename a file and put a special character in it, it completely cancels the file creation or file renaming when you try to save the name.
Instead, can it just create/rename the file without the special character? Perhaps with a small alert to remind us that Obsidian removed it? (Or at least please just prompt the user to fix their error, WITHOUT exiting the action and forcing us to start over?)
It’s especially irritating when typing out a detailed title with a lot of information. Add one special character, and your title reverts to what it was or your note doesn’t get created.
As most programs allow you to use more special characters in titles than Obsidian does, it’s easy to forget this limitation. Not having this stopgap can add up to a nontrivial amount of of wasted time and annoyance.
