Describe the bug

There is an issue with the "es.po" file in the repository where accents are not displaying correctly, appearing as "??" instead of the correct characters (e.g., "vac??o" instead of "vacío").

The problem is due to incorrect file encoding. I created a new file using Notepad with UTF-8 encoding, copied the content, and manually corrected the special characters.
