Notes that start with emoji in title cannot be exported as Markdown

[laurent22]

Sure, create a note and call it 💾 example. Then right-click on the note, select "Export" > "MD - Markdown," and choose a folder to export to. The target folder will be empty. Although two folders, "_resources" and "ALL," will be created, they won't contain any "md" files. Now, do the same process but remove the emoji from the note's title; the export will be done correctly, and the note will be exported as expected.

This works on Fedora Linux (Joplin 3.1.15). I'm re-tagging this with windows.
