Unicode Checker FAQ
What is a Unicode code point?
A code point is a unique number assigned to each character in the Unicode standard, written as U+XXXX (e.g. U+0041 for 'A'). There are over 140,000 code points covering all the world's writing systems.
Why are there invisible characters in my text?
Invisible characters like zero-width spaces (U+200B), non-breaking spaces (U+00A0), or control characters can be copied from websites or documents. The Unicode checker reveals them.
