Details:

Some TeX character sequences are a little tricky to decode thanks to MATLAB's
own way of doing TeX. Among those sequences is "\omega" whose subset "\o" is
also a sequence recognized by MATLAB. So if a string contains "\omega", does
that mean "(w)" or "(o)mega"?

It turns out that Octave is less consistent regarding that decision. While
MATLAB tries to match the longest known sequence, what Octave does depends on
what comes after the sequence. Example:


axes
title('\omega foo \omegabar \omega\alpha')


This yields "(w) foo (w)bar (w)(a)" in MATLAB but "(w) foo (o)megabar (w)(a)"
in Octave. In other words, if the character after the longest possible
sequence is a space or a backslash, the longest sequence is assumed to be
present. However, if the character after the longest possible sequence is a
letter, the shorter sequence is assumed to be present.

Other relevant cases:

* \o
** \omega
** \otimes
** \oplus
** \oslash
* \in
** \int
** \infty
* \subset
** \subseteq
* \supset
** \supseteq
