Frequently Asked Questions

What is Unicode escape?
Unicode escape is a notation like \u0041 that represents a Unicode character by its code point in hexadecimal. It's commonly used in JavaScript, JSON, Java, C#, and Python source code to embed non-ASCII characters safely.
What are HTML entities?
HTML entities are special sequences like © or © used to represent reserved or special characters in HTML documents. Named entities (e.g., &) use friendly names, while numeric entities use decimal (©) or hexadecimal (©) code points.
What is Punycode?
Punycode is an encoding used to represent internationalized domain names (IDN) with non-ASCII characters using only ASCII letters, digits, and hyphens. For example, "münchen.de" becomes "xn--mnchen-3ya.de". This allows DNS systems to handle domain names in any language.
What is the difference between Unicode code points and UTF-8?
A Unicode code point (e.g., U+4E2D) is the abstract number assigned to a character. UTF-8 is a variable-length encoding that represents code points as 1–4 bytes for storage and transmission. The same character has one code point but different byte sequences in UTF-8, UTF-16, etc.
Is my data sent to a server?
No. All conversion uses JavaScript running entirely in your browser. Nothing is transmitted to any server. Your data stays on your device.
