Apa yang dilakukan HTML Entity and Unicode Converter?
HTML Entity and Unicode Converter membantu mengodekan atau mendekodekan konten langsung di browser serta menjelaskan hasil dan batasannya dengan jelas. Kemampuan yang telah diverifikasi: 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.
Bagaimana cara menggunakannya?
- 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.

Kesalahan umum dan perbaikannya
| Gejala | Kemungkinan penyebab | Perbaikan |
|---|---|---|
| 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
Batas khusus alat ini: 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.
