SFTP private key (ppk) not loaded when file name has special characters

Reported by: Igor Akkerman Owned by:
Priority: high Component: FileZilla Client
Keywords: SFTP, UTF8, UTF-8, key, ppk, public, private, latin-1, iso-8859-1 Cc:
Component version: Operating system type: Windows
Operating system version: Windows 7 SP1

Description

In some cases a private key file (ppk) cannot be loaded from the file system to be used for SFTP authentification.

This happens when the ppk file name or the path to the ppk file have special characters like German Umlauts.

Whether the ppk file name is provided by the FileZilla or PuTTY settings is irrelevant.

Only exception: If 'iso-8859-1' is set as the charset of a connection in the Site Manager, the ppk file name is interpreted correctly.
