Thanks,
This unicode thing works like magic.
The only thing I am still unable to do is to insert the symbol \epsilon (as
distinct from \varepsilon).
For some reason, the varepsilon ε is printed fine, but a blank square is
printed instead of the lunate epsilon ϵ.
That is u' ε ' works, while u' ϵ' does not.
Any idea why this is happening ?
