Unicode → Characters
Decode codepoints back to text
The Unicode to Characters Converter is a clean developer utility designed to decode Unicode representation formats back into plain text. Supporting hex codepoints, decimal values, and escaped formats (like \uXXXX or HTML entities), it translates code strings back into readable characters in real-time.
When working with APIs, debugging databases, or analyzing network traffic, you often encounter escaped string literals or raw codepoints instead of readable text. Trying to translate these codes manually is slow and error-prone. This converter automates the process: paste your Unicode codes, and the decrypted text displays instantly.
All decoding runs locally in your web browser. No codes or decrypted text are sent to external servers, protecting your privacy and code. It is a secure, fast, and completely free developer utility designed for debugging and analysis.
Supported input formats
This decoder accepts a wide variety of Unicode formats. You can enter hex codepoints (with or without the "U+" prefix), decimal values, standard C/C++/Java/JavaScript escape sequences (\uXXXX), CSS escape codes, and HTML entities (like ©).
The parser automatically identifies the input format, splits multiple values, and processes them sequentially. This flexibility allows you to paste raw snippets directly from code files, logs, or databases, translating them into readable characters without manual formatting.
The decoding process
The parser processes the input code string, extracts the numerical values, and decodes them using JavaScript's native string conversion methods:
- Identify format (e.g., extract hex digits from
\u00A9or U+00A9). - Parse the numeric value:
Code = parseInt(HexStr, 16). - Convert value to character:
Character = String.fromCodePoint(Code).
Using fromCodePoint ensures that characters beyond the standard 16-bit range (such as emojis or complex symbols) are reconstructed correctly without surrogate pair bugs.
Worked decoding examples
Let us look at how the converter decodes common Unicode formats back into readable characters:
- Decoding JavaScript Escape:
- Input:
\u00A9\u00AE - Calculation: Parse
A9(169) andAE(174). - Output: ©®.
- Input:
- Decoding HTML Entities:
- Input:
😀😁 - Calculation: Parse 128512 (grinning face emoji) and 128513.
- Output: 😀😁.
- Input:
- Decoding raw Hex values:
- Input:
03B1, 03B2, 03B3(separated by commas). - Output: αβγ (Greek letters alpha, beta, gamma).
- Input:
When to use this decoder
Use this tool when debugging APIs that return escaped string payloads, analyzing log files containing unicode sequences, or verifying database records with raw codepoints. It is also an excellent resource for web developers decoding HTML entities from source files or inspecting localized text translations.
By automating the decoding process, it eliminates the need to look up codepoint charts manually or write one-off scripts. It is a quick, reliable debugging utility accessible on any device.
Invalid codes and formatting notes
The decoder requires valid Unicode inputs. If you enter invalid hex or decimal values, or formatting that the parser cannot recognize, the tool will display an error or omit the character. Additionally, note that some decoded Unicode characters may not render if your operating system or browser font lacks the corresponding glyph.
Additionally, ensure that you enter codepoint values rather than UTF-8 byte sequences. UTF-8 byte codes (like F0 9F 98 8A) represent the binary transmission format, while this tool expects the numerical Unicode index (U+1F60A), which is the standard format in programming strings.
Frequently asked questions
Can I mix input formats?
Yes. The parser is permissive and accepts mixed formats in the same input.
Why does my high codepoint not decode?
Most likely an invalid codepoint (above U+10FFFF) or a malformed escape. Valid Unicode codepoints go from U+0000 to U+10FFFF, with surrogate range U+D800–U+DFFF excluded.
How do I encode characters back to codepoints?
Use the Characters → Unicode tool.
What is the difference between fromCharCode and fromCodePoint?
In JavaScript, fromCharCode supports only 16-bit values up to U+FFFF. Extended characters (like emojis) are split into surrogate pairs, which fromCharCode cannot reconstruct. fromCodePoint supports all Unicode values up to U+10FFFF, preventing decoding bugs.
Why do some decoded symbols show up as empty boxes?
Empty boxes or question marks indicate that the character was decoded correctly, but your device's installed fonts do not contain the graphical glyph for that specific Unicode character.
