This seems misguided. The fact that 'ρ' isn't a pixel for pixel match for 'p' doesn't mean they're not confusable. The threat model is not being unable to solve a spot-the-difference puzzle. Unless you are familiar with every pixel of your system fonts, and carefully scrutinize every character on your screen, the lack of an exact match in jρmorgan[.]com in a URL is going to do very little for you. There are many english characters that have multiple totally distinct ways to write them, so you can have two 'a' variants that are distinct but equally 'normal' looking. I guess if you get an LLM to write your blog posts they don't have to make much sense to begin with.
