This doesn't compress the text any more than reducing font size does. The Shannon entropy is about the frequency with which each symbol occurs, not about what the symbols look like. This is just an alternate font and does not actually change symbol frequency, so the Shannon entropy will be the same as any other font. It's lossless unless you consider the possibility of symbol confusion, as it's pretty easy to produce strings that appear identical but are different, like how O and 0 are easily confused in many fonts.
