Accent character in folder name (é) causing unmapped folder

Description of issue:

I added an anime called “The Café Terrace and Its Goddesses”. I used Sonarr Series->Add New to find the anime listing online and create the directory, then moved my existing files into the directory and then updated the series. This worked well and the anime was added and monitored perfectly. However, I then noticed I have an unmapped folder entry, so I checked it out and it was the folder “The Café Terrace and Its Goddesses”. So I thought it might just be a one-off issue and deleted the series, which also cleared the unmapped folder entry. I re-added it the same way, and once again everything works as expected, but the unmapped folder entry again reports.

So I deleted it once again, but this time when I re-added it, I removed the accent character é from Café, (so now just Cafe). This added this series again just fine, and the unmapped folder issue did not occur.
