Hello

For the following example,

$$w∈ {C([0,T];H_{s,\delta} : \|w(0,\cdot )\|_{H_{s,\delta}} \leq  M_0,   w(t,x)\leq 0}$$

org-toggle-latex-fragment fails to generate a png

org-mime-htmlize fails as well but a separate bug report will be
submitted.

The above example works for Xemacs 21.5.34 and org 7.8.03!!

$$w\in {C([0,T];H_{s,\delta} : \|w(0,\cdot )\|_{H_{s,\delta}} \leq  M_0,   w(t,x)\leq 0}$$

works for me.

Maybe you need some encoding tricks to make your version work?

HTH,

Chuck

You are right, the evil ∈! Since I have started to use prettify-symbol
mode it is difficult to distinguish two situations:

    -   prettify-symbols, using overlays, *displays*  \in by  ∈

    -  but also \in can be *replaced* by the UTF8  ∈


After replacing the UTF8 by its latex constructions everything works
fine.

Sorry

I run into this problem quite frequently.  I often write with the tex
input method and later forget that I did so and ended up with UTF8
characters.

I wonder how difficult it would be to filter UTF8 characters that LaTeX
doesn't understand on export, e.g. converting ∈ to \in, maybe even using
the same org-entities table?  I'm sure a filter is straightforward in
emacs lisp, although beyond my capabilities unfortunately.
