There was also Michael Kaplan, who had a similarly informative and in-depth blog "Sorting it all out" about localization, text encodings, keyboard layouts etc in Windows. In fact, Raymond Chen specifically recommended him on these topics:

Unfortunately, Microsoft didn't exactly treat him kindly [1] in the end. And to add insult to injury, his blog was completely wiped. There are some archives around, but I haven't seen one that retained the images, which often makes the posts incomprehensible, unfortunately.
