Problem with charset and website builder

Hi! I hope I’m posting this in the correct section.

My site is in spanish, so it uses vowels with accents and the letter ‘ñ’. After uploading my files through the File Manager, I checked some of them (with the File Manager editor) and realized the accents and other special characters were converted to combinations of symbols (which didn’t work as equivalents). I just migrated from the old CPanel, so I thought the files scrambled with the downloads and uploads, and I started to correct everything manually (not many files, so no problem).

The problem is, even though the files worked (the accented vowels appeared as normal), when I go to check them there are symbols again. And if I correct something else from the same file, it works, but the older symbols convert to more symbols and then the previous corrections stop working.

I don’t know if I’m doing something wrong or what. Thank you for your help!
