Unicode X-Ray

Have you ever seen text around the internet that appeared to be using a different font in a place where that shouldn't be possible?

YouTube comment with letter-like characters
Text in comment, post, etc. where font controls are not available.

...or with strange marks around a character?

...or that was in a different script?

...or that looked like a picture (or emoji)?

Well, then you've seen the wide extent of Unicode characters. There are over 144,000 characters covered by the standard, each with their own semantics.

And that's where Unicode X-Ray may be helpful — it helps you take a look closer look at the characters you that you input:

  1. Provides names for characters, which help you understand how they're to be used.
  2. Links to reference material about each character and displays its unique identifier, called a codepoint.
  3. Performs grapheme clustering, where multiple characters attain another interpretation when they are combined. Each row represents one grapheme.
  4. Lets you normalize your input into different forms that may transform or reorder your text.

That's all. This is just a toy that helps me (and maybe you) answer, "How did they write that?" And all you have to do is copy & paste the text into this website.
