# noncharacters [](http://badge.fury.io/js/noncharacters)

> 34 non-character code points (labeled <not a character>), that are set aside and guaranteed to never be used for a character. Perfect to use for placeholders or temporary replacements during string transformations.
|
||
|
|
|
||
|
|
See the wikipedia [article on non-characters][wiki]. Also, I used [regenerate](https://github.com/mathiasbynens/regenerate) from [mathiasbynens](https://github.com/mathiasbynens) to generate the range of characters.
|
||
|
|
|
||
|
|
## Install with [npm](npmjs.org)
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm i noncharacters --save
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var noncharacters = require('noncharacters');
|
||
|
|
//=> ['\uFFFF', '\uFFFE', ...]
|
||
|
|
```
|
||
|
|
|
||
|
|
**Example**
|
||
|
|
|
||
|
|
Let's say you need to transform a string but you need to temporarily replace some characters that might cause issues.
|
||
|
|
|
||
|
|
Create your own placeholders:
|
||
|
|
|
||
|
|
```js
|
||
|
|
// arbitrary characters we want to replace,
|
||
|
|
// mapped to placeholder non-characters
|
||
|
|
var placeholders = {
|
||
|
|
'{': noncharacters[0],
|
||
|
|
'}': noncharacters[1]
|
||
|
|
};
|
||
|
|
|
||
|
|
// the string with characters to replace
|
||
|
|
var str = 'This is a template: {name}';
|
||
|
|
|
||
|
|
// actually replace the characters
|
||
|
|
Object.keys(placeholders).forEach(function(ch) {
|
||
|
|
str = str.replace(ch, placeholders[ch]);
|
||
|
|
});
|
||
|
|
//=> This is a template: \uFFFFname\uFFFE
|
||
|
|
```
|
||
|
|
Now you can do whatever you want to `str`. Then, to change back:
|
||
|
|
|
||
|
|
```js
|
||
|
|
Object.keys(placeholders).forEach(function(ch) {
|
||
|
|
str = str.replace(placeholders[ch], ch);
|
||
|
|
});
|
||
|
|
//=> This is a template: {name}
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
