You'd be forgiven for thinking that this translator converts text into a number of different fonts - that's not what's happening here. So how does it work? Unicode.
This translator is essentially generating unicode symbols which resemble letters from the latin alphabet (a, b, c, ...). Unicode is an international standard for symbols in computer-related industries. It supersedes "ASCII" and actually contains all the ASCII symbols within it's specification. There are literally tens of thousands of different symbols defined by Unicode compared to 256 characters defined by the extended ASCII set. On top of this, unicode allows us to add diacritic marks which agument our characters and allow us to produce weird stuff like this:
By the way, the above text is called "Zalgo text", and I also made a zalgo translator which you can use to generate that type of text.
So yeah, the unicode standard is awesome, and it allows us to have all sorts of fun with text.
I said earlier that this translator isn't simple generating the same text with a different font, it's actually generating different text symbols from the unicode spec. This has the awesome benefit that we can copy and paste symbols wherever we want (you couldn't do this if it were just a font). You might have found this generator after looking for a text to symbol converter which would allow you to have weird symbols in your profile like all the other l33t hackers.
L33t hacking aside though, weird text symbols of letters are great for making your message on social media stand out. Just look at the difference between:
> Look at my post!
> 𝓛𝓸𝓸𝓴 𝓪𝓽 𝓶𝔂 𝓹𝓸𝓼𝓽!
Since social media sites don't generally allow fonts, it gives the user a huge surprise when they see something new like that. So whether you want to put symbols in your Tumblr blogs, Facebook statuses, Twitter profiles or tweets, Instagram bios or wherever, this translator should hopefully be handy for that. Having different fonts Instagram bios has become fairly popular recently, so it might be worth jumping on that trend.
Are you looking for letters that aren't included in this generator? There are all sorts of different letters in Unicode, and I've done my best to include as many different symbol fonts as I can, but there is always room for improvement! If you find any different letters that I don't have, please let me know! I want to include as many different fonts as possible. Meanwhile, feel free to post a comment below with some crazy unicode symbols :)
