Registrar module - Change domain contacts with special characters

[Riccardo]

Hi all, 

We built a registrar module, for registrations and transfers we take the contacts information from $params['original'] in order to have the not transilterated version of the parameters and everything is working fine with special characters. 

I have issues in the function "mymodule_SaveContactDetails($params)".  When a customer submit the new information from the control panel for changing the contacts of the domain WHMCS passes to the module  also in the original array the transliterated version of the values. In this way if a customer registered a domain with an owner having a name "Tést" will be converted to "Test"  also if he only changes the address for instance. 

Can you help me to fix this issue? 

Example:

 

array (
  ......
  array (
    'registrant' => 
    array (
      'First Name' => 'Test',
      'Last Name' => 'ciao',
      'Company Name' => 'My company',
       .....
    ),
  'original' => 
  array (
    ......
    array (
      'registrant' => 
      array (
        'First Name' => 'Test',
        'Last Name' => 'ciao',
        'Company Name' => 'My company',
   ....
)
