&quot being stripped, why?

at one of my mods I settle the get_input to false, now I can paste a pure text on the page, but recently I noticed one thing: It still strips a few stuff.


I don't know if that's the market mod of if that's elgg which is causing it.

&quot is being stripped to a space (     ).

&quot means '', I supose it is being stripped due to security reasons, but once I settle up get_input to false, shouldn't it be left as it is?
