The default encoding for HTML used to be ISO-8859-1, not UTF-8, for HTML 4 and earlier (and could continue to be interpreted that way by NSAttributedString for compatibility). That could explain the extra character being displayed since the string you're passing as the HTML parameter to NSMutableAttributedString doesn't include, for example, a charset="utf8" meta tag in its <head> that would specify the desired encoding.

Copied from another project which uses an html document to be inserted into the NSTextView.
This project did have a database which did not have an HTML layout field and I forgot to change to NSAttributedString(string:s).
Found another DB which has an HTML data field (after I posted the original email), so I will drop my hand created version and use that.

I don’t deal with HTML much (besides basic websites) and completely forgot about the encoding.

Thanks for all the help.
