If you add a ' meta charset="UTF-8" ' inside your head it will remove the garbled quotation marks. It took me way too long to put that in my site, and I was manulally going back and changing characters to ascii ones before lol.
You have to put greater and less than symbols around meta charset="UTF-8" since Neocities doesn't like html in comments.
btw you can add HTML in comments, you just have to use escape characters. <meta charset="UTF-8"> is typed as <meta charset="UTF-8">
Thank you Yudo! Glad you like it <3
