Firefox causes an error "data encoding must be set to utf8 for listing"

[TomasHubelbauer]

When using Firefox to access ftp://localhost:1337/, the library throws the above error. The actual value of dataEncoding is binary. When I comment the check out, LIST works okay anyway.

It's Firefox setting this:

> TYPE I
OK: 200 Transfer type set to binary

Any way to address this?

Same problem with FileZilla

I commented it out and it worked successfully.

simple-ftpd/lib/requests/list.js

//   if (this.dataEncoding !== 'utf8') {
//     return this.respond(550, 'data encoding must be set to utf8 for listing')
//   }
