Support for code points on U+10000 to U+10FFFF

[redred82]

My test code statement is as follows:
TextOutW(hdc, 0, 0, L"\U0001F588 test", 5);

The font I installed is Symbola, the installation commands are as follows:
apt install fonts-symbola

Use the debian operating system and have the required fonts installed. Wine can display any character except the one I mentioned above. Please help

To add, this is a question about Supplementary Characters, A supplementary character is a character located beyond the Basic Multilingual Plane(in the range U+0000 to U+FFFF), See this in detail : https://docs.microsoft.com/en-us/window ... characters
This page mentions that:
The Windows GDI API supports format 12 cmap tables in fonts so that surrogates can be displayed correctly.

So the software that works well in the windows system is not working properly under wine, wine has BUG? Sorry, my English is poor.
