Why hello there internet adventurer! You've stumbled across an Old English font converter - a tool that lets you convert normal text into "old english" letters! These old style letters can be copy and pasted into your Instagram bio, and to other places around the web.
While I'm calling this fancy text style "Old English", it is actually called "Fraktur" - a typeface that originated hundreds of years ago in Rome. The design of the typeface was comissioned by a Roman emperor, and it quickly became popular and largely replaced the existing textual character designs that existed at the time. You might also hear these being called "Gothic" letters, and that's simply due to their popularity in medieval Germany. In fact, the Fractur font remained popular in Germany (and several other German-influenced European countries) right up until the 20th century. As it turns out, the font was actually banned by the Nazi Party of Germany in the 1940s because it was said to be "too Jewish".
But then how has it come to be included in Unicode? Well, Unicode began in the 1980s and set out to create a set of universal rules (a "universal code" --> Unicode) for converting binary to textual characters. The ASCII standard already existed for the basic characters, but there was a need for a larger standard that would cover all the needs of the coming digital revolution (including support for languages other than English, for example). Early users of the internet tended to be people from Academa, and many of these were mathematicians, so they had a fair degree of influence on which characters got included. And it was indeed the mathematicians that requested the Fractur (or "Old English", as we're calling it) text style.
Why? Because mathematicians often use this font style to represent certain mathematical objects, and they needed some way to send their equations to one another over the internet. So Unicode added a bunch of different "text fonts" that they could use.
Why not just let the mathematicians use actual fonts? Well, because you can't copy and paste fonts. So if you wanted to share an equation on a chat room that didn't have a Old English style font, then you were stuck. Having separate uicode characters for this gothic alphabet enabled people to very easily communicate their equations with a simple copy/paste.
So that's a brief history of how the Old English letters made their way into the Unicode standard, and thus how they're about to make their way into your Instagram bio :) You should me able to copy and paste them into a bunch of different social media platforms, but sometimes you may find that they don't display correctly, and unfortunately that's not something that can be fixed. With time though, most browsers and web pages should support these characters.
