R-/Text-editor for Windows?

Tinn-R (http://www.sciviews.org/Tinn-R/) is one of the topmost 
suggestions when googling an R-(text-)editor for Windows. However, 
to me it appears dissappointing that Tinn-R does not handle utf-8 
(mac-roman, or any other) encoded R-scripts or, in general, text 
files. Besides Emacs and the R built-in editor, could you 
recommend a good editor for Windows, even some commmercial for a 
small price? (For a comparison, TextMate for OS X is 35 USD and 
does a great job on all plain text and code related issues, not 
only R.) Thanks, *S*
