String decoding

[simonedd]

I have a file with some "special" characters, as in the following Beam definition. #857=IFCBEAM('3Lt4H72Y9CHQEeh3VllZNY',#6,'\S\Z\S\l. n\S\ametk. krokev',$,$,#821,#840,$);

After the parsing, the instance of the Beam is empty. {#857=IFCBEAM('3Lt4H72Y9CHQEeh3VllZNY',#6,$,$,$,$,$,$);}

Thanks.
