Special characters problem in "writeText" function.

[GoogleCodeExporter]

What steps will reproduce the problem?

First acknowledge you and the job, I am speaking Spanish and use the PDF
class, it turns out that when you have many special characters like "ñ, á,
é, í, ó and ú" loses the result of text and generates only one long line 
row.
This prevents you can generate the document, your help and you could verify
it is correct.
Thanks for your help. Greetings.
Text sample test:

myPDF.writeText (5,"Lorem ipsum máñana él día nótorio último Lorem ipsum

I found what the problem looks at the function where accumulates "l" and 
commented
code, and I am now working properly.        

public function writeText ( pHeight:Number, pText:String, pLink:String='' ):void
        {
            //Output text in flowing mode
            var cw:Object = this.currentFont.cw;
            var w:Number = currentPage.w-this.rMargin-this.x;
            var wmax:Number = (w-2*this.cMargin)*1000/this.fontSize;
            var s:String = str_replace ("\r",'',pText);
            var cwAux:int = 0;
            //var s:String = ",,,"
            var nb:int = s.length;
            var sep:int = -1;
            var i:int = 0;
            var j:int = 0;
            var l:int = 0;
            var nl:int = 1;

            while( i<nb )
            {
                //Get next character
                var c:String = s.charAt(i);

                if(c=="\n")
                {
                    //Explicit line break
                    this.addCell (w,pHeight,s.substr(j,i-j),0,2,'',0,pLink);
                    i++;
                    sep=-1;
                    j=i;
                    l=0;
                    if(nl==1)
                    {
                        this.x = this.lMargin;
                        w = currentPage.w-this.rMargin-this.x;
                        wmax= (w-2*this.cMargin)*1000/this.fontSize;
                    }
                    nl++;
                    continue;
                }
                if(c==' ') sep=i;
                /*          
                    Here verify if the character is unknown I value 500 by default, because the
problem is that if the character is not in the array can not add accumulator 
"l".

                cwAux = int(cw[c]);

We must correct the following function to operate the 'link' correct:

        private function GetStringWidth(s:String):Number

        {

            var s:String = String ( s );
            cw = currentFont.cw
            var w:Number=0;
            var l:int = s.length;
            var cwAux:Number = 0;
            for(var i:int=0;i<l;i++)
            {
                cwAux = Number(cw[s.charAt(i)]);

                if (isNaN(cwAux))
                {
                    cwAux = 500;
                }

                w+= cwAux;              
            }

            return w*fontSize/1000;

        }

Hi castromatias,

Thanks for tracking, I will include that and also optimize some other things 
related
to special characters in the next version ;)

kind regards,

Thibault

Hi, I'm trying to write text (using writeText function) with special spanish
characters (same as castromatias) from an utf-8 xml but I always get wrong 
results:
Ä, Â, etc... followed by another character.

I changed /WinAnsiEncoding encoding to all the posibilities (i think) but the 
result
is the same.

When I debug code I see correct characters in Flex but when pdf is generated 
everyone
turns wrong.

Thanks,

Fer
