* Parses phone number characters from a string.
|
|
* Drops all punctuation leaving only digits and the leading `+` sign (if any).
|
|
* Also converts wide-ascii and arabic-indic numerals to conventional numerals.
|
|
* E.g. in Iraq they don't write `+442323234` but rather `+٤٤٢٣٢٣٢٣٤`.
|
|
* @param {string} string
|
|
* @return {string}
|
|
* @example
|
|
* ```js
|
|
* // Outputs '8800555'.
|
|
* parseIncompletePhoneNumber('8 (800) 555')
|
|
* // Outputs '+7800555'.
|
|
* parseIncompletePhoneNumber('+7 800 555')
