Special characters in FTP files

I am having problems managing files on FTP when they have special characters. For example, file names with óor analogies.

I will give you an example. First, I want to list and process each folder file in FTP:

ftp = CType(FtpWebRequest.Create(sFtpPath), FtpWebRequest)
ftp.Method = WebRequestMethods.Ftp.ListDirectory
reader = New StreamReader(ftp.GetResponse().GetResponseStream())

files = reader.ReadToEnd.Split(New String() {NewLine}, StringSplitOptions.RemoveEmptyEntries)
reader.Close()

But this gives me problems when the file contains special characters, because the line that I have for the file does not exist on FTP, for example:

For Each sFich As String In files
    ftp = CType(FtpWebRequest.Create(sFtpPath & "/" & sFich), FtpWebRequest)
    ftp.Method = WebRequestMethods.Ftp.DownloadFile
    reader = New StreamReader(ftp.GetResponse().GetResponseStream())

    '...
Next

For example, a file EXAMPLE_aróon FTP is retrieved as here EXAMPLE_ar□, so when I try to upload a file, it says it does not exist.

How can I handle this?
