Issue: the Windows desktop app Sync feature replaces literal instances of “%20” with literal instances of a space in the names of files and folders when syncing.
Unidrectional sync results in, for example, “Bear%20Necessities” being copied as “Bear Necessities”.
Bidirectional sync results in the source being renamed to match its copy on the following pass.
This is using the Windows desktop app, v2.68, to sync folders. This issue is occurring on both Windows 10 Pro (21H2) and Windows Server 2008 Standard.
Copying files via Windows Explorer is unaffected.
EDIT: this behaviour further extends to other instances where a percent sign is followed by a number, e.g. “%21” is replaced with “!”. This may suggest an error involving Percent-encoding, also known as URL encoding.
