Convert text to Unicode code points, HTML entities or JavaScript escape sequences, and decode them back. Full astral-plane and emoji support.
Convert text to Unicode code points and back. Choose HTML entities, JavaScript escapes or U+ notation. Both panes are editable, and characters outside the Basic Multilingual Plane — including every emoji — are handled as single code points rather than surrogate pairs.
Unicode assigns every character a number called a code point, written U+ followed by hexadecimal digits. A is U+0041, 蜂 is U+8702, and the honeybee emoji is U+1F41D. That number is the character's identity. How it is stored — UTF-8, UTF-16, UTF-32 — is a separate decision, which is why this tool is distinct from the text-to-binary converter.
JavaScript strings are UTF-16. Code points above U+FFFF are stored as two 16-bit halves called a surrogate pair. Naive code that loops with charCodeAt sees an emoji as two meaningless values around 0xD800-0xDFFF and reports "🐝".length as 2. This converter iterates by code point, so the bee emoji produces one value, U+1F41D, not two broken halves.
A. Works in any HTML document and in XML.A. Same thing in hexadecimal, which matches how the Unicode charts are written.\u0041. For string literals in source code. Above U+FFFF the braced form \u{1F41D} is required, and the tool emits it automatically.U+0041. The form used in specifications and documentation.Escaping non-ASCII text as entities lets it survive systems that mangle encodings, such as older email gateways or misconfigured databases. Inspecting code points is also the fastest way to diagnose invisible characters: a zero-width space (U+200B) or a non-breaking space (U+00A0) looks identical to a normal space on screen but breaks string comparisons. Paste suspect text here and the difference is immediately visible.
