  if (ord($Str[$i]) < 0x80) continue; # 0bbbbbbb
  elseif ((ord($Str[$i]) & 0xE0) == 0xC0) $n=1; # 110bbbbb
  elseif ((ord($Str[$i]) & 0xF0) == 0xE0) $n=2; # 1110bbbb
  elseif ((ord($Str[$i]) & 0xF8) == 0xF0) $n=3; # 11110bbb
  elseif ((ord($Str[$i]) & 0xFC) == 0xF8) $n=4; # 111110bb
  elseif ((ord($Str[$i]) & 0xFE) == 0xFC) $n=5; # 1111110b
  else return false; # Does not match any model
  for ($j=0; $j<$n; $j++) { # n bytes matching 10bbbbbb follow ?
   if ((++$i == strlen($Str)) || ((ord($Str[$i]) & 0xC0) != 0x80))
