BUG: phi and varphi are not properly render in code / markdown

[jankoslavic]

I very much like the Jupyter Notebook. I found some strange behavior with varphi and phi in the cell..

To replicate the bug:

1. define a code cell and write \phi[press tab]. what will show up is actually \varphi
2. define a code cell and write \varphi[press tab]. what will show up is actually \phi
3. define a code cell and write \varphi[press tab] what will show up is actually \phi, but if you convert the cell to markdown it will show up as \varphi!

EDIT: I am using Chrome v60

I can't reproduce the problem, but I also see incorrect behaviour on Chrome
For reference, here are \phi and \varphi as rendered by latex:

With Chrome on Mac Os both are rendered as \phi, though in a sligthly different way:

With Firefox on Mac Os I instead see the correct behaviour (the same given by latex, as shown for example here):

With Safari on Mac Os \phi and \varphi are also rendered correctly:

I can reproduce this issue with Firefox 106 on Windows. I find this is (partly) because a wrong monospace font is used.

In my case, this is because the default monospace font is Consolas, and for some reason the designer of Consolas decided to use varphi as phi and vice versa.
