Emphasis issues with special blocks and latex

I am having several issues with the fontification of emphasis markers in
org-special-blocks and inside latex equations in my org-files.

I have changed `org-emphasis-regexp-components` to be the following...

```
  (with-eval-after-load 'org
    (setcar org-emphasis-regexp-components "\t('\"{[:alpha:]:-“”\[\\") ;;
chars for prematch
    (setcar (nthcdr 1 org-emphasis-regexp-components)
"\][:alpha:]-_^[:space:]:\t.,!?;''“”\")}/\\“”") ;; chars for postmatch
    (setcar (nthcdr 2 org-emphasis-regexp-components) "\\\\\t\r\n,\"") ;;
forbidden chars
    (setcar (nthcdr 3 org-emphasis-regexp-components) ".") ;; body
    (setcar (nthcdr 4 org-emphasis-regexp-components) 5) ;; max newlines
    (org-set-emph-re 'org-emphasis-regexp-components
org-emphasis-regexp-components))
```

I would like to be able to intersperse emphasis markers inside of strings,
which is why I included alphabetical characters for pre and post-match. I'd
like to be able to have *w*or*d* only bold the w & the d if possible, and
to be able to use backslashes between emphasized words (eg. ideally
=this=/d *be* /so//*cool*! should codify "this", italicize /so/, and bold
"cool*).

The main issue I get is that special-block metalines seem to get
font-locked (eg. `#+begin_theorem` becomes `#+begintheorem` and the
metalines themselves seem to cause the underlining of the contents within
the block. Inside latex equations, I end up with fontlocking if I don't
include spaces between underscores, pluses, minuses, or equal signs. I am
wondering if there is a way to fix this by adding more forbidden characters
(ie. forbid `#+begin_`, and `#+attr_latex` from being or causing emphasis,
and forbid emphasis between $$ $$, \begin{} \end{}, \( \), \[ \], $ $) or
possibly to include look-around using visual-regexp-sterioids.el.

Thanks in advance.
