//       discuss at: https://locutus.io/php/strrev/
//      original by: Kevin van Zonneveld (https://kvz.io)
//      bugfixed by: Onno Marsman (https://twitter.com/onnomarsman)
// reimplemented by: Brett Zamir (https://brett-zamir.me)
//        example 1: strrev('Kevin van Zonneveld')
//        returns 1: 'dlevennoZ nav niveK'
//        example 2: strrev('a\u0301haB')
//        returns 2: 'Baha\u0301' // combining
//        example 3: strrev('A\uD87E\uDC04Z')
//        returns 3: 'Z\uD87E\uDC04A' // surrogates
//             test: 'skip-3'
  string = string + ''
// Performance will be enhanced with the next two lines of code commented
// out if you don't care about combining characters
// Keep Unicode combining characters together with the character preceding
// them and which they are modifying (as in PHP 6)
// See https://unicode.org/reports/tr44/#Property_Table (Me+Mn)
// We also add the low surrogate range at the beginning here so it will be
// maintained with its preceding high surrogate
