This is with the Christmas (Santa Hat) beta.
I was trying to import a Wikipedia page: en.wikipedia.org/wiki/Juan_Rodr … z_Cabrillo
You’ll note the percent-hex escapes for the UTF-8 acute-accented-i in Rodríquez.
Trying other web page imports, the basic functionality appears to work well these days – including success on importing the base wikipedia.org page itself.
