Everything is in the title. I can pin them but in the pin section I see a blank line and I cannot access to the pinned note. See an example in the picture.
The special characters I am talking about seem to be accentuated characters:
é è à for me.
If you are wondering why I put accents and spaces in my file names, it is related to the fact that I use deft as a note manager in emacs: the title of the note is the file name.
Thank you for the extra information. I was on holiday last week, back now and will look into this for a fix in the next update.
