I'm hijacking this thread, since it seems to have the right heading. :lol:
These pages can be displayed on screen or printed out, but many of the characters with diacritics (especially the third tone ones) are not displayed properly on a standard Windows setup. I'd like to suggest a solution: instead of delivering them as formatted text, deliver them in pdf format (or provide this as an alternative), so that the pinyin characters are all displayed correctly. (Of course, the unusual sizes of paper used in North America may necessitate using two versions.)
On a similar note, I'd like to see the ?? shown in a larger font size than the romanised script, for two reasons - one is because the nature of these characters makes a larger font size appropriate, since they are more detailed (and if you start providing a version using traditional characters, as I think you intend to do at some stage, then that will be even more the case), and the other reason is that those of us that want to learn the Chinese characters (I think I can speak for everyone in this position) would prefer these to be more prominent than the romanised script.
