space characters sometimes are replaced by  

[pk-fr]

perhaps add   in the replace list
// replace some regexp
code = code.replace(new RegExp('<br/>', 'g'), '\n');
code = code.replace(new RegExp('<br>', 'g'), '\n');
code = code.replace(new RegExp('&lt;', 'g'), '<');
code = code.replace(new RegExp('&gt;', 'g'), '>');
code = code.replace(new RegExp('&amp;', 'g'), '&');
