Characters " []()" seem don't need to be escaped

[picrap]

The tests fail on pure-ftpd without escaping, and it's the ftp server I'm using 😄
Regarding FileZilla and STAT support, I am sorry about that, but there too, I'm using pure-ftpd and it supports this command.
In a more pragmatic way, what are your suggestions? Changing tests? Let me know if you have ideas, since they're always welcome.

I test with pure-ftpd v1.0.36 on CentOS 7, here is the result:

It seems only the "space" character is controversial.
But in any case, in my opinion, escape or not should be determined by user.
What do you think about this problem?

Currently I added a FtpPlatform which can be provided as a parameter to the FtpClient (via FtpParameters). You can provide your own implementation, in order to avoid any escaping.
Regarding the brackets and parenthesis, that's right, I made a blind fix for someone who had the problem (and the fix workd). Since it also works with other ftp servers, I keep the escaping, even if it is not always necessary.
So, I you don't have an objection, I'm going to close this issue.
Is it OK for you?

Yes, I have saw the constructor of FtpClient, it's OK to close this issue.
