page validation problem

I'm puzzled over a code validation issue I'm having right now.  Hoping you can check my code and advise how I can fix the issue.

The following page can't be validated through W3C:

 http://bookshelf.vamato.net/anotherworld.htm 

Here is the message from the validator:

Sorry, I am unable to validate this document because on line 1 it contained one or more bytes that I cannot interpret as windows-1252 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.

The error was: Modification of a read-only value attempted

I've gone over and over it, and copied and pasted the code (which appears identical to me) from other pages at my site that are validated, but I still keep getting the same message.

Something (?Windows update?) changed recently where I have to code in my smart quotes (instead of them just displaying as smart quotes if the original font had curly quotes).  But the location (Line 1) where the error apparently appears doesn't use any smart quotes in the code.  Especially since the error seems to be something in the very first line, it's frustrating and this is a recent change (yesterday) since I just uploaded a page 5 days ago that used the same code in the first line, and it validated.

I am using Windows 10 and the latest version of the Chrome browser (as far as I know).

I'm not a skilled coder, so simple explanations are greatly appreciated.  A friend set up my website originally, but I've been taking care of it and making my own pages for the past 12 years.  My friend can often spot thinks I did wrong if I can't see the mistakes myself, but she is out of the country right now.

Thank you for any help you can offer,
Mary Newton
