I wouldn’t do it myself. 
A user in Russia was getting a blank page. It took several hours to track down the cause and I couldn’t reproduce it until I set my browser’s encoding to Windows-1251.
I’m wondering if other Russian language users are experiencing blank pages. It’s apparently set on his computer at the OS level (Windows), and there isn’t an easy way to change a browser’s character encoding any more without some manual configuration. The browsers’ encoding auto-detection features aren’t working well. We tried Chrome and Firefox.
