GetGlyphOutline() and UTF-16 surrogate pairs

I'm using the GDI GetGlyphOutlineW function to get the outline of unicode characters, and it works fine except that it does not work with surrogate pairs (U+10000 and higher). I've tried converting the surrogate pair into a UTF-32 character, but this does not appear to work.

How can I get glyph outlines of Supplem开发者_运维知识库entary Multilingual Plane characters?

Some Suggestions:

• Does the particular Unicode code point you are trying to get actually exist in the font that is selected in the DC passed to the GetGlyphOutlineW function?

• Follow the directions on this page to enable surrogate pairs in Windows.

• Use the Uniscribe functions for character manipulation.
