Mate, what that does is totally throw away the IE8 rendering engine and replace it with the Google Chrome browser hidden in an IE interface. The reason it appears to be an "accelerator" is simple. Like we have been telling you all along, IE is crap.
Using Frame inside IE should be fine with Unicode here as long as you are using the site default theme. I'll add the meta tag into the other themes today. I hadn't bothered yet because I didn't think any one except me had even tested Frame.
