Support IE9/10 media hack?

[davatron5000]

Trying to use an IE9/10 specific @media screen and (min-width:0\0) hack (see "Moving IE specific hacks into media blocks") but StripMQ (what we use for IE8 support) is exiting with an error:

{ [Error: Stripping media queries failed.] origError: [TypeError: Cannot read property '1' of null] }

Would it be possible to support this weird hack? As a result, we'll have to degrade IE9/10 so that StripMQ can still work, but ideally StripMQ would maybe just ignore media queries it doesn't understand?

I think I lifted this hack from http://wtfforms.com: https://github.com/mdo/wtf-forms/blob/master/wtf-forms.css#L186-L212

Thanks!

Actually, 0\0 seems to work, the problem is when I pass this through sass I end up with 0 \0, which fails:

I will investigate to see if there's a way to prevent this behavior in sass. I don't see the point of supporting a malformed hack for IE here.

+1 for this issue with sass compiling causing stripmq to error.

In the meantime, I found a workaround using a slightly different IE Media Query hack which stripmq doesn't have such a problem with:

@media screen\0 {
  ....
}

Props to : http://keithclark.co.uk/articles/moving-ie-specific-css-into-media-blocks/media-tests/ for the media query hacks.
