Status: UNCONFIRMED

(Thunderbird :: Folder and Message Lists, defect)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:134.0) Gecko/20100101 Firefox/134.0

Steps to reproduce:

1. Have the Local Folders located in a folder containing diacritics, to confirm this issue I created a folder C:\Testășt (Romanian locale) and pointed Local Folders to it
2. Copy an email from Inbox to Local Folders
3. Open Local Folders, see the title of the email, the content is blanc
4. Try to open the email (double click)

Actual results:

Error message (ă is replaced with a, both ș and ț are replaced with _):

File not found

The file mailbox:///C:/Testa__/Inbox?number=1 cannot be found. Please check the location and try again.

Check the file name for capitalization or other typing errors.
Check to see if the file was moved, renamed or deleted.

Expected results:

The email is opened correctly. Some parts of Thunderbird can read the file path correctly (Local Folder settings, displaying the list of the mailbox) and other don't (showing the email content).

Probably different parts of the code use different character encoding.

Tested also in 135.0b2, doesn't work either, just that it display a white page instead of the error message
