The document has a mixture of RTL and LTR. xpdf determines the primary 
direction looking each unicode char, the predominant direction is RTL, so xpdf 
process all the text as RTL.


  // determine the primary direction
  lrCount = 0;
  for (blk = blkList; blk; blk = blk->next) {
    for (line = blk->lines; line; line = line->next) {
      for (word0 = line->words; word0; word0 = word0->next) {
    for (i = 0; i < word0->len; ++i) {
      if (unicodeTypeL(word0->text[i])) {
        ++lrCount;
      } else if (unicodeTypeR(word0->text[i])) {
        --lrCount;
      }
    }
      }
    }
  }
  primaryLR = lrCount >= 0;

We can determine the direction of each block of text looking for the unicode 
character type. But what happen if the file was created using RTL, including 
the LTR characters?.
