[Tex/LaTex] How to typeset a Fraktur x that looks like r

Question

How can I typeset this symbol?

And what is its name?

Answer 1

Pretty standard for old fraktur fonts for the "x" to be an "r" with a hook.

\documentclass{article}
\usepackage{amssymb}
\begin{document}
\begin{equation} 
\mathfrak{r}\mathfrak{x}
\end{equation}
\end{document}

Bringhurst tells us that blackletter fonts can be broken into 4 types, generally, based on how the lower case "o" is formed:

Here are some FRAKTUR examples exhibiting the x = r+ curl phenomenon:

Another type of blackletter font is BASTARDA (also known as Schwabacher). Some of them also follow this convention:

Here's one that has a bastarda "o", but mixes and matches styles from across the blackletter spectrum. Thus, I think it is a modern form

Next come the ROTUNDA fonts

These next two have the "r" + curl, but also adds an "x"-like stroke. Perhaps this was a transition type of design to the modern "x".

This extra stroke on the "x" is also almost universal in the TEXTURA fonts:

Finally there is this one, that seems to elude categorization:

Whew... and that is only my blackletter fonts that exhibit this characteristic "x" as an "r" variant. If you haven't guessed, I like fraktur and other blackletter fonts. To show what a nut I am, I actually started characterizing letters by their construction. Then, by looking at which constructions the fonts had, I could group them appropriately, or even tell imposters.

As you can see, I ran out of steam before getting around to differentiating the "x".
