Look like it is a bug with the "passed by reference", so altered the code:

$ diff  Idna.php  Idna.orig
42,43c42
<             $zero = 0;
<             return idn_to_ascii($data, $zero, INTL_IDNA_VARIANT_UTS46);
---

67,68c66
<                         $zero = 0;
<                         $part = idn_to_utf8($part, $zero, 
INTL_IDNA_VARIANT_UTS46);
---
 >                         $part = idn_to_utf8($part, 0, 
INTL_IDNA_VARIANT_UTS46);

Thanks,
