I noticed equations with "<"'s weren't displaying correctly in HTML
export using mathjax. The attached patch fixes this by html-encoding
latex fragments for mathjax HTML export. I imagine this change would be
generally useful and could be applied to master.
Best,
Eric

I am a bit puzzled. I just tried exporting the following buffer:
\(1 < 2\)
and the result looked good. Could you provide an example of a failed
export?

See

for some gotchas.

Thanks, the link does describe the problem well. My particular problem
formula included "i<d" in part of a larger equation.
From the link above it sounds like replacing just "<", ">" and "&"
should be sufficient, if the full html encoding in my previous patch was
too heavy weight.
Best,

By default, `org-html-encode-plain-text' just takes care about "<", ">"
and "&", which is what you're looking. However, it is configurable
through `org-html-protect-char-alist', which may cause trouble.
FWIW I think a hard-coded function dedicated to the task, or simply
a hard-coded replacement within `org-html-format-latex', may be safer in
the long run. Anyway Rick Frankel may have an opinion here.
Regards,

Not sure why `org-html-protect-char-alist' is a custom and not just a
var, but IMHO, `org-html-encode-plain-text' is the correct solution.

I made `org-html-protect-char-alist' a defvar.
