    To convert the utf16 or utf8 decimal values (utf-8 can translate both encodings) to ascii characters using mb_ord, follow these steps:
    Starting value:
    1_Zvpxs4pf
    Value converted to decimal value utf-16 or utf-8 (see ascii coding table):
    49,95,90,118,112,120,115,52,112,102
    recovery with mb_ord:
    use: $ char = mb_chr ($ decimalValue, 'UTF-8');
    return the correct character;
    1, _, Z, v, p, x, s, 4, p, f
    example:
    $ start_String = 1_Zvpxs4pf;
    $ start_String_to_Decimal = 49959011811212011552112102;
    (decimal value of each character add in an array);
    $ tab = [49, 95, 90, 118, 112, 120, 115, 52, 112, 102];
    $ size = sizeof ($ tab);
    $ tmpStr = '';
    for ($ i = 0; $ i <$ size; $ i ++)
    {
    $ tmpStr. = mb_chr ($ tab [$ i], 'UTF-8');
    }
    echo $ tmpStr;
    1_Zvpxs4pf
