Function decodeFilterArg

decodeFilterArg(arg: string, removeAccents?: boolean): string
Helper for decoding HTML-encoded symbols inside a string.

This is almost a generic decoder for HTML-encoded symbols, supporting decimal and hexadecimal codes, plus optional removal of accents (diacritical marks) from letters. However, it does not support HTML entity names, like &, etc., as its main purpose is to decode filter arguments (not full HTML documents), so it prioritizes performance over universality.
Parameters
- arg: string
  A string that contains HTML-encoded symbols, like this:
  
  { - decimal symbol code (1-6 digits);
  
  ƣ - hexadecimal symbol code (1-5 hex digits, case-insensitive);
- removeAccents: boolean = false
  Optional accents (diacritical marks) removal from letters, if truthy. Default is false.
Returns string
Decoded string.
Example
```
import {decodeFilterArg} from 'custom-string-formatter';

decodeFilterArg('some &#x28;text&#x29;'); //=> some (text)

decodeFilterArg('sòmê &#60;téxt&#62;'); //=> sòmê <téxt>

decodeFilterArg('sòmê &#60;téxt&#62;', true); //=> some <text>
```
