6.6 Simplified ToUnicode Interface

idna_to_unicode_4z4z

Function: int idna_to_unicode_4z4z (const uint32_t * input, uint32_t ** output, int flags)

input: zero-terminated Unicode string.

output: pointer to newly allocated output Unicode string.

flags: an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

Convert possibly ACE encoded domain name in UCS-4 format into a UCS-4 string. The domain name may contain several labels, separated by dots. The output buffer must be deallocated by the caller.

Return value: Returns IDNA_SUCCESS on success, or error code.

idna_to_unicode_8z4z

Function: int idna_to_unicode_8z4z (const char * input, uint32_t ** output, int flags)

input: zero-terminated UTF-8 string.

output: pointer to newly allocated output Unicode string.

flags: an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

Convert possibly ACE encoded domain name in UTF-8 format into a UCS-4 string. The domain name may contain several labels, separated by dots. The output buffer must be deallocated by the caller.

Return value: Returns IDNA_SUCCESS on success, or error code.

idna_to_unicode_8z8z

Function: int idna_to_unicode_8z8z (const char * input, char ** output, int flags)

input: zero-terminated UTF-8 string.

output: pointer to newly allocated output UTF-8 string.

flags: an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

Convert possibly ACE encoded domain name in UTF-8 format into a UTF-8 string. The domain name may contain several labels, separated by dots. The output buffer must be deallocated by the caller.

Return value: Returns IDNA_SUCCESS on success, or error code.

idna_to_unicode_8zlz

Function: int idna_to_unicode_8zlz (const char * input, char ** output, int flags)

input: zero-terminated UTF-8 string.

output: pointer to newly allocated output string encoded in the current locale’s character set.

flags: an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

Convert possibly ACE encoded domain name in UTF-8 format into a string encoded in the current locale’s character set. The domain name may contain several labels, separated by dots. The output buffer must be deallocated by the caller.

Return value: Returns IDNA_SUCCESS on success, or error code.

idna_to_unicode_lzlz

Function: int idna_to_unicode_lzlz (const char * input, char ** output, int flags)

input: zero-terminated string encoded in the current locale’s character set.

output: pointer to newly allocated output string encoded in the current locale’s character set.

flags: an Idna_flags value, e.g., IDNA_ALLOW_UNASSIGNED or IDNA_USE_STD3_ASCII_RULES.

Convert possibly ACE encoded domain name in the locale’s character set into a string encoded in the current locale’s character set. The domain name may contain several labels, separated by dots. The output buffer must be deallocated by the caller.

Return value: Returns IDNA_SUCCESS on success, or error code.
