Code (1)

\begin{equation}
\mu (B)= \sup \{\mu(K): K\subset B, \mbox{ $K$ compact} \}\, 
\end{equation}

produces (but see below!):

\begin{equation} \mu (B)= \sup \{\mu(K): K\subset B, \mbox{ '"`UNIQ-MathJax2-QINU`"' compact} \}\, \end{equation}

as compared to the code (2):

\begin{equation}
\mu (B)= \sup \{\mu(K): K\subset B, K \mbox{ compact} \}\, 
\end{equation}

which produces:

\begin{equation} \mu (B)= \sup \{\mu(K): K\subset B, K \mbox{ compact} \}\, \end{equation}

Interestingly, if code (1) is put inside $ ... $, it renders correctly, however it does not so, if it is put inside \[ ... \].
