-/** Convert byte order of an array encoded in UTF(8/16/32) to system endianness in place.
- *
- * Uses the UTF byte-order-mark (BOM) to determine UTF encoding. If there is no BOM
- * at the beginning of array, UTF-8 is assumed (this is compatible with ASCII). The
- * BOM, if any, will be removed from the buffer.
- *
- * If the encoding is determined to be UTF-16 or UTF-32 and there aren't enough bytes
- * for the last code unit (i.e. if array.length is odd for UTF-16 or not divisible by
- * 4 for UTF-32), the extra bytes (1 for UTF-16, 1-3 for UTF-32) are stripped.
- *
- * Note that this function does $(B not) check if the array is a valid UTF string. It
- * only works with the BOM and 1,2 or 4-byte items.
- *
- * Params:
- *
- * array = The array with UTF-data.
- *
- * Returns:
- *
- * A struct with the following members:
- *
- * $(D ubyte[] array)            A slice of the input array containing data in correct
- *                               byte order, without BOM and in case of UTF-16/UTF-32,
- *                               without stripped bytes, if any.
- * $(D UTFEncoding encoding)     Encoding of the result (UTF-8, UTF-16 or UTF-32)
- * $(D std.system.Endian endian) Endianness of the original array.
- * $(D uint bytesStripped)       Number of bytes stripped from a UTF-16/UTF-32 array, if
- *                               any. This is non-zero only if array.length was not
- *                               divisible by 2 or 4 for UTF-16 and UTF-32, respectively.
