I’m on Windows 7 Home Premium so I couldn’t try.

> Now, if you have the UI displayed in (say) English, then it is not the primary fonts that matter for CJK but rather what is used as fallback fonts. If you change the system locale setting (the "Language for non-Unicode programs" -- on the Administrative tab in the Regional and Language Options control panel) to one of the Chinese options, then the order in which fonts will be used in much of the shell will change. So, by default for an English system, the primary UI font is Segoe UI, and Meiryo UI will be the first font that gets tried if a UI string has CJK; but if you change the system locale to (say) Chinese (Simplified, China), then Microsoft YaHei will be the first font used for CJK.

Yes, I managed to change the system locale to Chinese (Simplified,
China). In a few programs this resulted in the desired display of
simplified-style characters, but I didn’t like the side effects like
changes in font family names (e.g. "微软雅黑" instead of "Microsoft
YaHei"). I later reverted to the old settings.

> Note that changing system locale will impact what you see in much of the shell and in certain text controls used in apps (e.g. the main doc window in Notepad), but it won't affect text in all scenarios -- e.g. on an (unstyled) web page or in Wordpad.
> If you have a font that supports Shavian, there is something you can try to get it used as a fallback font, though this is not a scenario that was tested in Win7: if you're comfortable making changes in the Windows Registry, then go to this key
> HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\LanguagePack\SurrogateFallback
> And add a string entry with the name "Plane 1" and a value which is the name of your font (the font family name, not the file name). (There used to be a KB article about this mechanism, but I haven't seen it in a long while. Given the nature of changes made in certain parts of the text stack in Win7, I won't guarantee it would still work.)

I also changed this key in the registry. However registering a Plane 1
font containing glyphs for Shavian did not lead to any apparent change.

Thanks a lot any way,
