    thanks very much for this.

    I want to confirm my understanding, and with your permission I'll
    include your remarks below on my page for supporting surrogates.

    1) The possible explanation then for the difference between Andrew and
    myself with respect to the need for a special registry setting, is that
    Andrew most likely installed something, perhaps a language pack, that
    caused Uniscribe to be loaded on his system. He therefore didn't need
    the setting. I probably didn't install anything that used Unsicribe.

    2) The first paragraph describes a registry value that forces Uniscribe
    to load.
    I presume that you are referring to the first of these two entries
    recommended by the kbase. The second seems specific to IE. Is that
    presumption that this entry causes Uniscribe to be loaded correct?

    [HKLM]\SOFTWARE\Microsoft\Windows NT\CurrentVersion\LanguagePack]

     IEFixedFontName=[Surrogate Font Face Name]
     IEPropFontName=[Surrogate Font Face Name]

    3) For XP only, we can set a font face name that supports surrogates
    into this registry entry. Doing so will make this font the default for
    plane 1 characters, if another font is not explicitly designated to be


    (and by extension for the other planes).

    cool. thanks

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.

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:
