Unicode Code Points to Text

What this Unicode Code Points to Text tool does

This converter parses code-point notation, validates every parsed value as a Unicode scalar value, and builds decoded text with String.fromCodePoint(). It supports U+ notation, plain hexadecimal, decimal values, 0x values, HTML numeric references, JavaScript escapes, Python escapes and CSS escapes. Processing runs locally in the browser.

Supported input notation

Supported examples include U+0041 U+00E9 U+1F600, 0041 00E9 1F600, 65 233 128512, 0x0041 0x00E9, A, A, \u{41}, \u0041, \U0001F600 and CSS escapes such as \41 . Auto-detect is conservative: it accepts distinctive syntax and reports ambiguous or mixed input instead of guessing.

What is a Unicode scalar value?

A Unicode scalar value is any code point from U+0000 through U+10FFFF except the surrogate range U+D800 through U+DFFF. Surrogate values are reserved for UTF-16 internals and are rejected as standalone input.

Code points and UTF-16 surrogate pairs

U+1F600 is one Unicode code point for 😀. In legacy JavaScript UTF-16 escape syntax, the same character may be written as \uD83D\uDE00. This tool combines valid surrogate pairs into one scalar value and rejects isolated or reversed surrogate escapes.

Supplementary characters

Supplementary characters are above U+FFFF. Examples include U+1F600 → 😀, U+1F9D1 → 🧑 and U+20000 → 𠀀. They are converted as full code points rather than truncated UTF-16 units.

Combining marks and normalization

U+0065 U+0301 decodes to decomposed é. With normalization off, that exact sequence is preserved. If you explicitly select NFC, the decoded text may normalize to precomposed é. Normalization is a separate post-conversion option and is off by default.

Emoji and ZWJ sequences

The sequence U+1F468 U+200D U+1F469 U+200D U+1F467 U+200D U+1F466 may render as the family emoji 👨‍👩‍👧‍👦. Several code points can form one grapheme cluster, and every code point is preserved in order.

Invisible and control characters

Decoded text may contain U+0000 NULL, tabs, line feeds, carriage returns, no-break spaces, zero-width characters, variation selectors and bidirectional controls. The tool preserves valid scalar values and reports unusual invisible or format characters in warnings and diagnostics.

Invalid input

Malformed prefixes, missing semicolons, invalid hexadecimal digits, values above U+10FFFF, surrogate values, isolated UTF-16 surrogates, mixed formats and ambiguous plain values are reported as errors. The parser does not silently repair malformed notation.

How to use the tool

Select the input notation, paste code points or escapes, choose the token separator policy, and process. Load example uses the selected notation. To generate U+ notation from ordinary text, open Text to Unicode Code Points.

Privacy and processing

This tool runs in your browser. Your input is not submitted to UnicodeNow, inserted into URLs, saved to localStorage or sessionStorage, or sent through analytics by this page.

Common uses

• Converting U+ notation to text.
• Testing emoji sequences.
• Reconstructing combining-character sequences.
• Decoding HTML numeric references.
• Testing JavaScript and Python escapes.
• Inspecting invisible characters.
• Validating Unicode scalar values.
• Debugging surrogate-pair problems.

Examples

Input:

U+0048 U+0065 U+006C U+006C U+006F U+002C U+0020 U+00E9 U+0020 U+1F600

Output:

Hello, é 😀

Combining input:

U+0065 U+0301

Output:

é

Emoji sequence input:

U+1F468 U+200D U+1F469 U+200D U+1F467 U+200D U+1F466

Output:

👨‍👩‍👧‍👦

The emoji output contains several code points but may display as one grapheme cluster.
