I use `\url` which does not require to escape characters in an URL to make 
them acceptable for latex (specifically LuaLaTex). However when the same 
reference is included in a footnote, characters (especially `_` and `%` 
seem to required escaping. Am I missing somehting? 

Here a MWE: 

```
\documentclass[]{article}

\usepackage{url}

\begin{document} 

Phoenizisch \url{https://de.wikipedia.org/wiki/Unicodeblock_Ph%C3%B6nizisch}
    and more text
    with the same ref in a footnote%
 \footnote{some text with the same url
          \url{{https://de.wikipedia.org/wiki/Unicodeblock_Ph%C3%B6nizisch}}
        and a closing text.}%
    . After the footnote 

\end{document}

```

which does not compile with the error 

```
File ended while scanning use of \@footnotetext.

```

It does, of course, compile and produce output as expected if the offending 
url in the footnote is removed. Note that the same url in the body is 
processed correctly. I assume that there is an interaction between `\footnote` and `\url`. 

What is the best solution or workaround?
