Escaping characters in batch scripts

Question

I have the following script to automate uploading a file to a remote server. The problem is that the password I entered is filled with special characters that kill the login process.

Here is the modified version of the characters:

J7 ~]% & X

Using a regular FTP application is not a problem. I wrapped the password in quotation marks and also tried to use ^it to avoid percent and ampersand. However, this does not work. In addition, I can’t say which password is being sent.

What can happen wrong or how can I open a password before sending it?
