Unicode.utf16_ToUtf8

Convert a string from UTF-16 to UTF-8. The result will be terminated with a 0 byte. Note that the input is expected to be already in native endianness, an initial byte-order-mark character is not handled specially. g_convert() can be used to convert a byte buffer of UTF-16 data of ambiguous endianess. Further note that this function does not validate the result string; it may e.g. include embedded NUL characters. The only validation done by this function is to ensure that the input can be correctly interpreted as UTF-16, i.e. it doesn't contain things unpaired surrogates.

Parameters

str gunichar2*

a UTF-16 encoded string

len glong

the maximum length (number of gunichar2) of str to use. If len < 0, then the string is nul-terminated.

itemsRead glong

location to store number of words read, or NULL. If NULL, then G_CONVERT_ERROR_PARTIAL_INPUT will be returned in case str contains a trailing partial character. If an error occurs then the index of the invalid input is stored here.

itemsWritten glong

location to store number of bytes written, or NULL. The value stored here does not include the trailing 0 byte.

Return Value

Type: string

a pointer to a newly allocated UTF-8 string. This value must be freed with g_free(). If an error occurs, NULL will be returned and error set.

Throws

GException on failure.
