How can I make cool font by my own for copy and paste?

I’ve had the same issue with some of those tools, especially when certain Unicode characters aren’t supported properly on different devices.

One option you could try is https://alphafonts.com/. It offers different copy-and-paste text styles, so you can type your text, choose a style, and copy the result directly into social media profiles, posts, or comments. I’d recommend testing a few styles across the platforms you use, since Unicode-based fonts can still display differently depending on the device or app.

For readability, I’d stick with simple bold, serif, sans-serif, or typewriter-style options rather than the overly decorative ones.
