GLib.ucs4_to_utf16

function ucs4_to_utf16(str: String, len: Number(glong), items_read: Number(glong), items_written: Number(glong)): Number(guint16) {
    // Gjs wrapper for g_ucs4_to_utf16()
}

Convert a string from UCS-4 to UTF-16. A 0 character will be added to the result after the converted text.

str: a UCS-4 encoded string
len: the maximum length (number of characters) of str to use. If len < 0, then the string is nul-terminated.
items_read: location to store number of bytes read, or null. If an error occurs then the index of the invalid input is stored here.
items_written: location to store number of #gunichar2 written, or null. The value stored here does not include the trailing 0.
Returns: a pointer to a newly allocated UTF-16 string. This value must be freed with GLib.free. If an error occurs, null will be returned and @error set.
