I've been noticing that the org-pretty-entities code incorrectly lexes
numbers as part of TeX command names; for example, if I type $\sim2n^2$, the
\sim will not be replaced with a ~ because the 2 is lexed as part of the
command name.  This is incorrect; in TeX, numbers are not legal parts of a
command name.

Here's a patch that fixes the issue:

diff --git a/lisp/org.el b/lisp/org.el
