Hi, I have just upgraded to 4.2 and I am having problem with LaTeX
typesetting in text cells. greek letters are not typeset but
otherwise, the rest of the latex is formatted normally.
here is one of my latex expressions:
$$ \begin{eqnarray} \lambda&= & \beta(I+eta A)\\ \frac{dS}{dt} &=& \mu
- (\lambda+\mu)S, \\ \frac{dE}{dt} &=& \lambda S - (\epsilon+\mu)E\\
\frac{dI}{dt} &=& \alpha \epsilon E + \alpha \sigma \lambda R - (\tau
+\mu)I\\ \frac{dA}{dt} &=& (1-\alpha)\epsilon E + (1-\alpha) \sigma
\lambda R - (\tau+\mu) A\\ \frac{dR}{dt} &=& \tau I + \tau A - R
(\sigma \lambda+\mu)\\ \frac{dIa}{dt} &=& \alpha \epsilon E + \alpha
\sigma \lambda R\\ \end{eqnarray}$$
in this example the equation array looks normal but the greek letters
are replaced by random unicode characters.
This is undoubtedly a font problem, but how can I check this and
potentially fix it?
thanks,
FLávio
