Hi people i have a problem with line break...
I have a text and when i generate the PDF the context don't have line break and the word be split wrong like that:


O seminário, realizado pelo Instituto Euvaldo Lodi (IEL), em parceria com o Conselho Setorial d
a Indústria Mineral da Federação das Indústrias do Estado do Paraná (Fiep), fez parte do ciclo de 13 ev
entos realizados no mês de novembro sobre meio ambiente, micro e pequena indústria, setor mo
veleiro e mineral.

if you see the word "d line break a" after Conceslo setorial is wrong because that word "da" need be all in the other line not be splited. What i can do ?

I had the same problem with each line containing non latin non punctuation charaters (such as em dash, en dash, degree symbol, etc.). 

I wasn't able to trace the problem to its root, but the problem seems to occurs in text_frame_decorator.cls.php, in function split_text, around line 127.

Basically, the internal encoding of the DOMDocument loaded appears to be ISO-8859-1 in my case, but the nodes' content are UTF-8. The DOMText::splitText function seems to go fubar because of that.

I did solve my problem with the following hack. It's a hack because I did not find where exactly the problem originates, but I cancelled its effect in a later stage. Therefore, this is no bug fix.

I replaced this code (n text_frame_decorator.cls.php, in function split_text, around line 127) :

--
  function split_text($offset) {
    if ( $offset == 0 )
      return;
    
    $split = $this->_frame->get_node()->splitText($offset);
    $deco = $this->copy($split);
--

by this:

--
  function split_text($offset) {
    if ( $offset == 0 )
      return;
    
    $text = $this->_frame->get_node()->nodeValue;
    
    $split = $this->_frame->get_node()->splitText($offset);
    $this->_frame->get_node()->nodeValue = mb_substr($text,0,$offset);
    $split->nodeValue = mb_substr($text,$offset);
    $deco = $this->copy($split);
--

Works for me, with all the weird characters I'm using.

Cheers,

Tommy.
