Here is another link about the matter:

I have been following this topic, but due to other commitments, I haven't had time to participate. But I contacted one of the techies, whose mother tounge is Spanish, and asked about the two upper case letters that didn't validate. Here is the reply I got:
"Hi Inger! I have taken a look and I cannot see those kind of errors with those characters, not on his pages neither on mine (https://validator.w3.org/nu/?doc=http%3 … index.html). Only thing I can think of is that he has copied those characters from another source. For example I noticed MS Word documents transforms a bit the chars, like using a different “angled tick” which it could be not valid indeed (even though those should be transformed in SD).
so maybe if you could ask him to post the actual link of the validator with the issue maybe will give a hint… but from a quick glance it should not be an issue."
Note what he says about copying/ pasting text from MSWord. Don't know if you did that, of course.

I'm glad Inger has an answer about the characters, as I could find nothing further to help on that.

I believe that iframes (as contrasted with frames) are still fine, but frameborder, if used, should be in a CSS file rather than in the element tag for the Nu HTML Checker not to show an error.

The element affected in SD4 is the Video Platform element. The HTML5 Video element appears not to be affected. Indeed, I have just had the following reply from the CoffeeCup team:

"Site Designer uses a type of hack to be able to make the embedded video link from a third party source responsive. If validation is important to you then using the HTML5 Video element would be the alternative."

All the styling that automatically comes with iframes can be taken off and added in the page manager instead. You need to first add them to the 'pm', then save and export your files, and finally remove those styles from the exported files. I usually never bother with that, though.

Hi Inger,
Nope. Typed in SD. I did another trial in CC HTML manager. I attach the document in a zip and also the resultant validation. It is just a plain html with 2 paragraphs and the Á and Í typed in. If you all don't have the issue, I am wondering, whether it could be hardware (keyboard) related. But then, I obviously use a spanish keyboard on my microsoft surface.

For the moment I resolved the issue by just using a plain "A" and "I", so you won't see those errors on my pages right now.

Another possibly easier option would be to use the html element and make a styled custom component for embedded video.

BTW, I moved the spanish legal text out to its own page and now NU accepts my page language for all the english pages.

Or perhaps use the HTML5 Video element as suggested by the CoffeeCup team.

I opened UTF8_test.html in The HTML Editor and tested it using Document > 'Validate HTML Using Old Checker...' and it showed everything as fine.

It seems that the codes U+0081 and U+008D may subsequently have been deprecated for the characters in question and that they are replaced by U+00C1 and U+00CD (https://www.utf8-chartable.de/unicode-u … p;utf8=dec).

Is it possible that the Spanish keyboard in use is using out-of-date codes for utf-8 purposes?

It is a surface Pro 5 keyboard. All updates are current. I would be surprised, if that was the problem, but one never knows.
What happens if you type it on your keyboard? Does it validate on the new validator?
