#62 No access to files with % in file name

[Kallisto]

Steps to reproduce:
1. Create non-empty file with % in the name in FTP server directory. Let's say, 'File%3f.txt'.
2. Mount FTP directory as a filesystem with the command like 'curlftpfs ftp://login:password@192.168.168.1:2121/ /tmp/ftp'.
3. Go to the mounted directory 'cd /tmp/ftp'.
4. List the files 'ls -l'. Take a note that 'File%3f.txt' listed correctly.
5. Try to open the note with a text editor. Access violation occurred. Other files could be opened without problems.
