HandleData Final letter analysis for logical-visual decision.

Look for evidence that the received buffer is either logical Hebrew or visual Hebrew. The following cases are checked: 1) A word longer than 1 letter, ending with a final letter. This is an indication that the text is laid out "naturally" since the final letter really appears at the end. +1 for logical score. 2) A word longer than 1 letter, ending with a Non-Final letter. In normal Hebrew, words ending with Kaf, Mem, Nun, Pe or Tsadi, should not end with the Non-Final form of that letter. Exceptions to this rule are mentioned above in isNonFinal(). This is an indication that the text is laid out backwards. +1 for visual score 3) A word longer than 1 letter, starting with a final letter. Final letters should not appear at the beginning of a word. This is an indication that the text is laid out backwards. +1 for visual score.

The visual score and logical score are accumulated throughout the text and are finally checked against each other in GetCharSetName(). No checking for final letters in the middle of words is done since that case is not an indication for either Logical or Visual text.

The input buffer should not contain any white spaces that are not (' ') or any low-ascii punctuation marks.
