For some reason during long editing sessions in Sublime the text file occasionally loses its Unicode encoded status. I have had to open the file in another editor to save it back to it's Unicode encoded state. Can you add Unicode to your "save with encoding" and "open with encoding" options .
I tried to use "http://sublimetext.userecho.com/" as directed in "Submitting Feature Requests " topic but, it hangs on the initial page. Is it only me?
