Windows does that properly? I guess a testcase would be nice, did you run into that using a certain program?
There is no such problem on Windows. I was in the East Eighth District yesterday. The time you replied was early morning at 01:30am, so I couldn't reply your message in time.I'm sorry. I wrote a demo of a windows program, which is used to input an emoji ???? (U+1F34A), and the Textout API is used here to output characters (Textout directly calls ExtTextout in wine), and ExtTextout accepts WCHAR * characters String (0xD83C, 0xDF4A), here involves "surrogate_pai", which uses four bytes to represent a character, but I looked at the implementation of ExtTextout, he only accepts two bytes each time, so he thinks that a four-byte is two Two bytes, so ???? cannot be output. Because wine thinks that all unicode is two bytes（0xD83C） to represent a character, so there will be many other problems here, such as GetTextExtentPoint32W will get the wrong character width. At the same time, if I use "宋体" as the output font, ???? this character has no corresponding glyph in the font, windows will use other fonts for output（font fallback）, and accurately calculate the font width (for line breaks, etc.), but wine will use the font you set (宋体) to calculate the width, I haven't written a corresponding demo about this issue -- Do not reply to this email, post in Bugzilla using the above URL to reply.

I don't see U+1F34A being supported in Noto Sans CJK SC. Might be worth trying e.g. U+1F200.
You are right, U+1F34A are not supported in Noto Sans CJK SC. But I checked the source code, the problem is not that there is no corresponding glyph of U+1F34A in Noto Sans CJK SC, but that the str accepted by ExtTextOutW is in UTF-16 format, so U+1F34A is converted into 0xD83C and 0xDF4A, a loop is used to traverse the str string, so U+1F34A is considered as two separate characters. like:
ExtTextOut get WCHAR *str -> {0xd83c,0xdf4a,0}
for(int i = 0; i < count; i++) find_glyph_from_font(font,str[i])
By the way, Using the ScriptString API in wine, the problem can be solved very well, but I don't think this modification is perfect. We also need to get GetTextExtentPoint32W to return the correct character width when dealing with surrogate pairs -- Do not reply to this email, post in Bugzilla using the above URL to reply.
