|

* <ul>
|
||||
* <li><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 <code>UBiDi</code> when the
|
||||
* reordering mode is set to <code>UBIDI_REORDER_DEFAULT</code>. Visual RTL
|
||||
* mode is not supported by <code>UBiDi</code> and is accomplished through
|
||||
* reversing a visual LTR string,</li>
|
||||
* <li><visual input, logical output>: unless the input direction is RTL, this
|
||||
* corresponds to an "inverse bidi algorithm" in <code>UBiDi</code> with the
|
||||
* reordering mode set to <code>UBIDI_REORDER_INVERSE_LIKE_DIRECT</code>.
|

* Visual RTL mode is not not supported by <code>UBiDi</code> and is

* reordering mode set to <code>UBIDI_REORDER_RUNS_ONLY</code>; and if the
|
||||
* input and output base directions are identical, the transformation engine
|
||||
* will only handle character mirroring and Arabic shaping operations without
|
||||
* reordering,</li>
|
||||
* <li><visual input, visual output>: this reordering mode is not supported by
|
||||
* the <code>UBiDi</code> engine; it implies character mirroring, Arabic
|
