/**
 * 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')
