RE: Entering Plane 1 characters in XP
There are multiple registry keys that can cause usp10.dll to load. So usp10.dll may be loading even though you've deleted the LanguagePack key (not recommended, btw). Also, an application can load usp10.dll, independently of what the OS does. I suspect that's what you are seeing on Win98. There is a performance penalty for loading usp10.dll. Some of the core text display functions become a tad slower because of the additional processing. John -Original Message- From: Andrew C.

Thanks for the explanation. I've got all the language packs installed, which probably explains why I don't need to set the Registry on W2K as specified by Microsoft. But for my Windows 98 machine all I did was put USP10.dll in the system directory, and Unicode friendly apps are able to display surrogates (using Code2001). Like everyone else I've copied the Registry mantra given by Microsoft in "http://msdn.microsoft.com/library/default.asp?url=/library/en-us/intl/unicode_192r.asp"; into my surrogates page (http://uk.geocities.com/BabelStone1357/Unicode/surrogates.html), but I can't say I understand what app uses the [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\LanguagePack] registry key and when. I deleted this key yesterday on my W2K machine, and rebooted it, and IE6 is still displaying surrogates OK. Leaving aside why one earth Microsoft would want to disable surrogates by default in the first place, can anyone explain what exactly they mean by "Windows disables surrogate support by default" ? How "disable" ? IE only ? Andrew

I'll have somebody a bit more familiar with IE registry usage review that part, but the rest looks good. Thanks.

Re: Entering Plane 1 characters in XP
Andrew, it is definitely a requirement for some applications. However, it would not be surprising if applications overtime have made themselves independent of the registry entry. I do know that to view my plane 1 example web page with IE, the registry needed to be set on both win 2k and win xp. http://www.i18nguy.com/unicode-example-plane1.html If I get some time later I'll play with unsetting it and see what happens now. tex "Andrew C.

RE: Entering Plane 1 characters in XP
Concerning display, there are two separate registry settings: - in Windows 2000 and Windows XP, you can set a registry value to cause Uniscribe to load (Uniscribe is required to display supplementary characters). Alternatively, you could install any of the language packs that require Uniscribe. The only difference between Windows 2000 and Windows XP in this regard is that XP installs Uniscribe for East Asian languages, whereas 2000 installed it only for complex scripts. - Windows XP added a feature to provide font-linking for supplementary characters if Uniscribe is loaded. There are 16 registry values, each of which designates a font for a plane. Although the mechanism exists, none of the registry values are set in Windows XP. Without this registry value set, you must explicitly select the font which contains the glyphs for the supplementary characters. The registry value for Plane 1 is: HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\LanguagePack\SurrogateFallback\Plane1 Windows 2000 and Windows XP will otherwise treat supplementary characters identically e.g. sorting by code point order.
