/**
* 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')
* ```
