Unterminated string literal error
March 20, 2012 03:50PM

I am a happy HTMLPurifier for quite some time now but the last couple of days I've been puzzling why the following pasted text after being cleaned by HTMLpurifier breaks and causes a Javascript 'unterminated string literal' error on return from mySQL.

Dirty code 

<span> 
Some text here. &#8232;
</span>

Cleaned 

<span> 
Some text here. ?
</span>

Although it looks cleaned and the pipeline is completely UTF-8 for some reason it seems the silent killer &#8232 / u2028 (Line Separator) is still there even though I don't see it. If I would output it in a page everything looks normal but when using it in Javascript it will fail.

Does anyone have a suggestion on what I should do? Trying to Preg_replace it with PHP before giving it to HTMLPurifier or is there a $config I don't know about?

So maybe regex and replace with the escape codes?

Alternatively, yell at whoever is encoding your JSON to handle this correctly.
