ANSIBLE: Split function not removing the '\r' carriage return from string

I have a local txt file called file-names.txt that contains a list of filenames

file1.txt
file2.txt
file3.txt

In my ansible-playbook I'm registering the file contents of file-name.txt using the slurp module. And setting a fact named files_names.

tasks:
 - name: Getting the file
   ansible.builtin.slurp:
    src: file-name.txt
   register: file_names
 - name: Saving the file names
   set_fact: 
     file_name_list: "{{ (file_name['content] | b64decode | trim ).split('\r\n') }}"

I want the file_name_list fact to be a list just containing the file names. but some how split function is not able to remove the '\r' from the file names and I get the following results

ok: [localhost] => {
  "ansible_facts":{
     "file_name_list": [
       "file1.txt\r",
       "file2.txt\r",
       "file3.txt"       
      ]
  },
  "changed": false
}

How can I remove the carriage return '\r' from each element of the array so that file_name_list looks like

ok: [localhost] => {
  "ansible_facts":{
     "file_name_list": [
       "file1.txt",
       "file2.txt",
       "file3.txt"       
      ]
  },
  "changed": false
}

PS: file-name.txt was made on a Windows machine, that's why there is a carriage return included in each line.

So the trim filter seems to be removing the final \r from the list of files on file3.txt. So instead of using trim before splitting, we can trim each item after splitting the filenames with \r.

Something like below should do the trick:

    - name: saving the file names
      set_fact:
        filename_list: "{{ filename_list|default([]) + [ item|trim ] }}"
      with_items: "{{ (filenames.content|b64decode).split('\r') }}"
    - name: show the filenames
      debug:
        var: filename_list

This should produce:

ok: [localhost] => {
    "filename_list": [
        "file1.txt",
        "file2.txt",
        "file3.txt"
    ]
}
