 if the most recent strongly directional character
 is an Arabic letter (its Bidi direction value is RIGHT_TO_LEFT_ARABIC). 
 The initial state at the start of the text is assumed to be not an Arabic,
 letter, so European digits at the start of the text will not change.
 Compare to DIGITS_ALEN2AN_INIT_AL.

<DL>
<DD>Construct ArabicShaping using the options flags.
 The flags are as follows:<br>
 'LENGTH' flags control whether the text can change size, and if not,
 how to maintain the size of the text when LamAlef ligatures are 
 formed or broken.<br>
 'TEXT_DIRECTION' flags control whether the text is read and written
 in visual order or in logical order.<br>
 'LETTERS_SHAPE' flags control whether conversion is to or from
 presentation forms.<br>
 'DIGITS' flags control whether digits are shaped, and whether from
 European to Arabic-Indic or vice-versa.<br>
 'DIGIT_TYPE' flags control whether standard or extended Arabic-Indic
 digits are used when performing digit conversion.

   does not validate the text against the options, for example, 
   if letters are being unshaped, and spaces are being consumed
   following lamalef, this will not detect a lamalef without a 
   corresponding space.  An error will be thrown when the actual
   conversion is attempted.
