/**
 * `UBiDiOrder` indicates the order of text.
 *
 * This bidi transformation engine supports all possible combinations (4 in
 * total) of input and output text order:
 *
 * - <logical input, visual output>: unless the output direction is RTL, this
 * corresponds to a normal operation of the Bidi algorithm as described in the
 * Unicode Technical Report and implemented by `UBiDi` when the
 * reordering mode is set to `UBIDI_REORDER_DEFAULT`. Visual RTL
 * mode is not supported by `UBiDi` and is accomplished through
 * reversing a visual LTR string,

 * Performs transformation of text from the bidi layout defined by the input

 * <ul>
 * <li>calling <code>ubidi_setReorderingMode</code> as needed (when the
 * reordering mode is other than normal),</li>
 * <li>calling <code>ubidi_setInverse</code> as needed (when text should be

 * <li>resolving embedding levels of each character in the input text by

 * <li>reordering the characters based on the computed embedding levels, also
 * performing character mirroring as needed, and streaming the result to the
 * output, by calling <code>ubidi_writeReordered</code>,</li>
 * <li>performing Arabic digit and letter shaping on the output text by calling
 * <code>u_shapeArabic</code>.</li>

 * An "ordering scheme" encompasses the base direction and the order of text,
 * and these characteristics must be defined by the caller for both input and

 * There are 36 possible combinations of <input, output> ordering schemes,
 * which are partially supported by <code>UBiDi</code> already. Examples of the

 * <ul>
 * <li><Logical LTR, Visual LTR>: this is equivalent to calling
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_LTR</code>,</li>
 * <li><Logical RTL, Visual LTR>: this is equivalent to calling
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_RTL</code>,</li>
 * <li><Logical Default ("Auto") LTR, Visual LTR>: this is equivalent to
 * calling <code>ubidi_setPara</code> with
 * <code>paraLevel == UBIDI_DEFAULT_LTR</code>,</li>
 * <li><Logical Default ("Auto") RTL, Visual LTR>: this is equivalent to
 * calling <code>ubidi_setPara</code> with
 * <code>paraLevel == UBIDI_DEFAULT_RTL</code>,</li>
 * <li><Visual LTR, Logical LTR>: this is equivalent to
 * calling <code>ubidi_setInverse(UBiDi*, true)</code> and then
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_LTR</code>,</li>
 * <li><Visual LTR, Logical RTL>: this is equivalent to
 * calling <code>ubidi_setInverse(UBiDi*, true)</code> and then
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_RTL</code>.</li>
 * </ul>
 * All combinations that involve the Visual RTL scheme are unsupported by
 * <code>UBiDi</code>, for instance:
 * <ul>
 * <li><Logical LTR, Visual RTL>,</li>
 * <li><Visual RTL, Logical RTL>.</li>
 * </ul>

 * the object will be allocated by the engine on the fly.
 * @param src A pointer to the text that the Bidi layout transformations will
 * be performed on.
 * Note: the text must be (at least)
 * <code>srcLength</code> long.
 * @param srcLength The length of the text, in number of UChars. If
 * <code>length == -1</code> then the text must be zero-terminated.
 * @param dest A pointer to where the processed text is to be copied.
 * @param destSize The size of the <code>dest</code> buffer, in number of
 * UChars. If the <code>U_SHAPE_LETTERS_UNSHAPE</code> option is set,
 * then the destination length could be as large as
 * <code>srcLength * 2</code>. Otherwise, the destination length will
 * not exceed <code>srcLength</code>. If the caller reserves the last
 * position for zero-termination, it should be excluded from
 * <code>destSize</code>.
 * <code>destSize == -1</code> is allowed and makes sense when
 * <code>dest</code> was holds some meaningful value, e.g. that of
 * <code>src</code>. In this case <code>dest</code> must be
 * zero-terminated.
 * @param inParaLevel A base embedding level of the input as defined in
 * <code>ubidi_setPara</code> documentation for the
 * <code>paraLevel</code> parameter.
 * @param inOrder An order of the input, which can be one of the
 * <code>UBiDiOrder</code> values.
 * @param outParaLevel A base embedding level of the output as defined in
 * <code>ubidi_setPara</code> documentation for the
 * <code>paraLevel</code> parameter.
 * @param outOrder An order of the output, which can be one of the
 * <code>UBiDiOrder</code> values.
 * @param doMirroring Indicates whether or not to perform character mirroring,
 * and can accept one of the <code>UBiDiMirroring</code> values.
 * @param shapingOptions Arabic digit and letter shaping options defined in the
 * ushape.h documentation.
 * Note: Direction indicator options are computed by
 * the transformation engine based on the effective ordering schemes, so
 * user-defined direction indicators will be ignored.
 * @param pErrorCode A pointer to an error code value.
 *
 * @return The destination length, i.e. the number of UChars written to
 * <code>dest</code>. If the transformation fails, the return value
 * will be 0 (and the error code will be written to
