This solves nothing.

Moscow rules.

This is not sophisticated, but will give you an idea how to really hide a message if you want to.

My message is in bold:

You should not fear your benevolent government, who
can use a variety of means to protect you. Bad people can
easily use our communications systems for bad purposes and can
hide their bad intent in encrypted messages or
a simple email. The government has the technology to find this
message and stop these nasty people from harming us,
if they didn't, then two stupid boys from Chechnya might hurt
you. So don't fear the government, they only
want to help you. So, there are ways to hide a message if you want
to.

Do you see it?
You can easily hide a message if you want to.

It won't work. Email is sent as ASCII character codes; not as images of letters. When you see a particular font, that's because there's HTML formatting included in the email. But the underlying message is still quite readable to a machine. To make a font like this work, you would have to send the message as an image file; difficult, but not impossible to read.

[Lonesome in Massachussets]

Why not just use ROT13, which is just as secure?

[Beckwith]

This is ridiculous.

The NSA has more cryptologists per square foot that any entity in the world. If you invent an entirely new font, they’ll have it countered within the week

And how does this concept affect voice transmissions?

[Lazamataz]

Immediately, the NSA would simply adapt their readers to accomodate this changed font.
