Was macht HTML Entity and Unicode Converter?
HTML Entity and Unicode Converter hilft dabei, Inhalte zu kodieren oder zu dekodieren. Die Verarbeitung erfolgt im Browser und Grenzen werden klar beschrieben. Geprüfte Funktionen: HTML entity encoding, Entity decoding, Unicode escapes, Code-point inspection.
Encoding is not sanitization
Use entities to display reserved characters as text in an HTML text or quoted-attribute context. Use a maintained HTML sanitizer when users are allowed to submit markup, because safe elements and attributes require policy decisions.
Wie wird es verwendet?
- Choose entity encode/decode, Unicode escape encode/decode, or List code points.
- Enter text or encoded values; the result updates immediately.
- Verify the output context before copying it into HTML, JavaScript, CSS, or another language.
Echtes Ein- und Ausgabebeispiel
Escape markup-significant characters
Eingabe
<b title="A&B">Café</b>Ausgabe

Häufige Fehler und Korrekturen
| Symptom | Wahrscheinliche Ursache | Korrektur |
|---|---|---|
| Encoded text is still unsafe in an event handler or script block. | HTML entity encoding alone does not cover JavaScript, CSS, URL, or attribute-policy risks. | Use context-aware escaping and a trusted sanitizer or templating system for untrusted HTML. |
| Unicode decode leaves an escape unchanged. | The input is not a four-digit \uXXXX escape or a \u{...} code-point escape. | Correct the escape syntax and ensure the value is a valid Unicode code point. |
Important behavior of HTML Entities
Konkrete Grenze dieses Werkzeugs: Entity encoding prevents characters from being interpreted as markup; it is not a complete HTML sanitizer.

HTML Entities — FAQ
Does the HTML Entities upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the HTML Entities accept?
It accepts plain text, HTML entities, or JavaScript-style Unicode escapes. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the HTML Entities produce?
It produces entities, decoded text, Unicode escapes, or a code-point list. Copy and download controls appear when the output format supports them.
What limitation should I know?
Entity encoding prevents characters from being interpreted as markup; it is not a complete HTML sanitizer.
