I searched a lot but no where i found how to remove the non ascii character with the relevant normal character. Many of the posts i found removing of asii character from the string using php. It is just the solution for remove only. If the string contain both non asii and ascii character eg: BË€. On removing of non ascii character from that string i get only the output of B. Its not the better output, the best output is BEE. We must replace the non ascii character or non-printable character with the relevant character. At last i found the solution to fixed that. Kindly watch it below.

Example:

 echo translateNonasciiToNormal($string);
 function translateNonasciiToNormal($string) {

    $text = $string;

    // Single letters
    $text = preg_replace("/[∂άαáàâãªä]/u",      "a", $text);
    $text = preg_replace("/[∆лДΛдАÁÀÂÃÄ]/u",     "A", $text);
    $text = preg_replace("/[ЂЪЬБъь]/u",           "b", $text);
