Unicode Inspector
Unicode issues can be surprisingly hard to see. Two characters may look similar while using different code points, a string may contain invisible whitespace, or an emoji may occupy multiple UTF-16 code units. The CodeToolia Unicode Inspector lets you type or paste a character and inspect its code point, UTF-8 bytes, UTF-16 units, HTML entity, and URL-encoded value. It is useful when debugging copy-paste bugs, international text, emoji handling, slug generation, database encoding, and frontend rendering differences. The tool runs locally and is intentionally focused on making a single character easier to understand.

About Unicode Inspector
Inspect Unicode code points, UTF-8, UTF-16, HTML entities, and URL encoding. This utility is part of CodeToolia, a collection of tools designed to simplify web development workflows. Like all our utilities, this tool operates entirely on the client side, meaning your data is processed locally within your browser and is never transmitted to any server.
Privacy & Security
We prioritize your privacy. By using browser-based technologies (Web APIs), we ensure that sensitive data—such as API keys, JSON payloads, or personal identifiers—stay strictly within your local environment.
How to use
- Enter one character or symbol in the input field.
- Review Unicode, UTF-8, UTF-16, HTML entity, and URL encoded values.
- Use the values when debugging rendering or encoding problems.
How this tool works
Unicode Inspector is designed around a simple rule: keep the transformation visible, reversible when possible, and easy to verify before the result leaves your browser. Many developer utilities look small because the interface is only an input and an output, but the value comes from reducing uncertainty in a frequent workflow. This tool gives you a focused place to inspect the data, run the operation, and compare the result without opening a large IDE, writing a one-off script, or sending the value to a remote API.
The implementation runs on the client side and is intentionally narrow. That matters for encoding tools because developers often paste examples from logs, staging systems, documentation, browser consoles, or API clients. A local-first workflow lowers friction and keeps the page useful even for quick checks. It also makes the behavior easier to reason about: the input you see is the input being processed, and the output is produced immediately in the same session.
Common use cases
Use Unicode Inspector when you are debugging a request, preparing a code example, building a fixture, reviewing a copied value, or checking whether a teammate's sample behaves the way you expect. It is especially helpful during small interruptions in a normal development day, when switching context to a heavier tool would take longer than the actual operation.
The page is also useful as a teaching and documentation aid. You can paste a short sample, show the result, and then copy the output into an issue, pull request, test case, or internal note. Because the surrounding page includes examples, related tools, and FAQ entries, users who arrive from search can understand not only what the tool does, but also when the result should be trusted and when a more specialized workflow is appropriate.
Example
Input: ✓ Unicode: U+2713 HTML entity: ✓ URL encoded: %E2%9C%93
Accuracy and privacy notes
Treat the output as a practical development aid rather than a substitute for production validation. Different platforms may apply slightly different rules, especially around encodings, browser APIs, timestamps, redirects, regular expressions, and security-sensitive data. For important production changes, verify the result in the same runtime, framework, or service that will consume it.
Avoid pasting private credentials, personal data, or production secrets into any online tool unless you fully control the environment. CodeToolia tools are built to process values locally in the browser, but careful data handling is still a good engineering habit. When sharing examples publicly, replace real identifiers and sensitive fields with safe sample values.
FAQ
Can emoji use more than one code unit?+
Yes. Many emoji require surrogate pairs or multiple code points.
What is UTF-8?+
UTF-8 is a variable-length byte encoding for Unicode text.
Why inspect invisible characters?+
Hidden spaces and control characters can break matching, slugs, and validation.
