INTL_MAX_LOCALE_LEN
     (integer)
     
    -

IDNA_DEFAULT
     (integer)
     
    - 
     
      Prohibit processing of unassigned codepoints in the input for IDN
      functions and do not check if the input conforms to domain name ASCII rules.
     
    
 
   
   
    - 
     
IDNA_ALLOW_UNASSIGNED
     (integer)
     
    - 
     
      Allow processing of unassigned codepoints in the input for IDN functions.

IDNA_CHECK_BIDI
     (integer)
     
    - 
     
      Check whether the input conforms to the BiDi rules.
      Ignored by the IDNA2003 implementation, which always performs this check.
     
    
 
   
   
    - 
     
IDNA_CHECK_CONTEXTJ
     (integer)
     
    - 
     
      Check whether the input conforms to the CONTEXTJ rules.

     (integer)
     
    - 
     
      Option for nontransitional processing in
      idn_to_ascii(). Transitional processing is activated

    - 
     
IDNA_NONTRANSITIONAL_TO_UNICODE
     (integer)
     
    - 
     
      Option for nontransitional processing in
      idn_to_utf8(). Transitional processing is activated
      by default. This option is ignored by the IDNA2003 implementation.

      Use IDNA 2003 algorithm in idn_to_utf8() and
      idn_to_ascii(). This is the default.
      This constant and using the default has been deprecated as of PHP 7.2.0.
     
    
 
   
   
    - 
     
INTL_IDNA_VARIANT_UTS46
