The logical to visual conversion takes place in the function:

  FRIBIDI_API fribidi_boolean
  fribidi_log2vis (FriBidiEnv *fribidienv,
                                               /* input */
                                              const FriBidiChar *str,
                                               FriBidiStrIndex len,
                                               FriBidiCharType *pbase_dirs,
                                               /* output */
                                               FriBidiChar *visual_str,
                                               FriBidiStrIndex
*position_L_to_V_list,
                                               FriBidiStrIndex
*position_V_to_L_list,
                                               FriBidiLevel
*embedding_level_list);

You just pass in a UCS-4 encoded string in logical order and it is
output in visual order. You may pass in NULL for the FriBidiEnv. The
function returns any of for entities if the pointers passed in are
NULL.

The tests are done by translating back and forth between ASCII and
certain Unicode characters (internally called CapRTL) so that the
functionality of reordering may be tested with Latin characters only.
