Hello,

Indeed, this was discussed in this ML. We need some escape character in
Org. A general escape character is a bit ambitious, and not necessarily
useful, but we could introduce one specifically for verbatim and code
markers, much like in macros and verbatim blocks, e.g.

  ~some\~code\=with special\\ characters~

There is a design decision involved: what character can be escaped? It
could be anything, or limit to "~" for code and "=" for verbatim
markers. For example macros limit escape-able characters to "," and "\".
This makes the contents easier to read, but the rule is inconsistent.

Thoughts?

It's because Org recognize LaTeX commands only if they are followed by
a blank character, the end of buffer, or "{}", which is not the case
with \verb@...@.
