|
|
console.log(entities.encodeNonUTF('<>"\'&©®')); // <>"'&©®
|
|
console.log(entities.encodeNonASCII('<>"\'&©®')); // <>"\'&©®
|
|
console.log(entities.decode('<>"'&©®∆')); // <>"'&©®∆
|
|
```
|
|
|
|
**All HTML entities encoding/decoding**
|
|
|
|
|
|
```javascript
|
|
const Entities = require('html-entities').AllHtmlEntities;
|
|
|
|
const entities = new Entities();
|
|
|
|
console.log(entities.encode('<>"&©®∆')); // <>"&©®∆
|

|
|
```
|
|
|
|
**Available classes**
|
|
|
|
```javascript
|
|
const XmlEntities = require('html-entities').XmlEntities, // <>"'& + &#...; decoding
|
|
Html4Entities = require('html-entities').Html4Entities, // HTML4 entities.
|
|
Html5Entities = require('html-entities').Html5Entities, // HTML5 entities.

|
|
```

Supports four methods for every class:
|
|
|
|
* encode — encodes, replacing characters to its entity representations. Ignores UTF characters with no entity representation.
|
|
* encodeNonUTF — encodes, replacing characters to its entity representations. Inserts numeric entities for UTF characters.
|
|
* encodeNonASCII — encodes, replacing only non-ASCII characters to its numeric entity representations.
|
|
* decode — decodes, replacing entities to characters. Unknown entities are left as is.
