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 ?
