What is View > Character Encoding set to? In my installation it's set to UTF-8.

The default encoding is usually set to Western (ISO-8859-1) to be used when the server doesn't send an encoding and no encoding is specified otherwise.

Which encoding is used on the pages that aren't displaying properly?

Note that if the server sends an encoding and a different encoding is specified via a meta tag on BOM (Byte Order Mark) in the file that Firefox will always use the encoding send by the server.

Thank you both. The view coding was set to the default. I have now changed it to Unicode (UTF-8) and the pages display correctly.

It would be best to fix this on the server or with a meta tag in the file(s) if the server doesn't send an encoding rather than changing the default encoding in Firefox as this can cause problems on other web pages that rely on a western or windows encoding and may show "?" instead.

Thanks. The pages are on my computer. They are notes and bookmarks which I have created as html pages so that I can view them in my browser and open links in them.

I will look into the matter of putting a meta tag in the pages. I have no knowledge of that.

Thanks for your help.

I have implemented the meta tag suggestion. Thanks again.
