How to convert EBCDIC with Spanish accent to English in RUST

Question

If the string contains truly Spanish accents in UTF8, I could use unidecode()

let x = unidecode("ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðñòóôõöùúûüýÿ");    
println!("reading file: {}", x);
// output = SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy

However, I am working mainframe output file in EBCDIC format, if I view it in redhat terminal, I see "Mu�oz". If I ftp the file to OSX and view it in TextEdit, I see "MuÒoz". There are some encoding in the TextEdit when viewing ....

The utf8 Spanish accents should be C392 in Hex, but I got F1 from mainframe file. How can I convert � to Ò and then O, and for all other Spanish accents?

+++

utf8 Spanish accents = Ò = C392 (Hex) = ﺃφ

EBCDIC Spanish accents = � = F1 (Hex) = ﹼ

If I use unidecode(), it changes "Mu�oz" to "Muoz". I want to convert "Mu�oz" to "MuoOz".

I tried both ISO_8859_10 encoding ...it converted "Mu�oz" to "Muïŋ―oz". Now, I am questioning whether it is EBCDIC encoded file that I am getting ...

let file_in = File::open("infile").unwrap();
    let mut file_out = File::create("outfile").unwrap();

    let mut decoded_stream = DecodeReaderBytesBuilder::new()
        .encoding(Some(ISO_8859_10))
        .build(file_in);

    std::io::copy(&mut decoded_stream, &mut file_out).unwrap();
