The font fallback from either Windows or mIRC is using hardcoded name fonts which don't exist on your system, the result you see in channel is probably the two surrogates which are used to form the emoji character in utf16. Your currently selected font does not have the emoji.

The channel window actually attempts to print it as two characters. This is how the grinning face emoji shows up in the channel window and edit box: But it really doesn't matter, because I can choose literally any font and the result is the same: it doesn't work. I've had this installation for quite a few years so it's seen a bunch of upgrades.

My OS is Xubuntu 23.04 (and it being Xubuntu it of course uses XFCE Desktop Environment). I can't get any emojis to work, so let's just give a simple example: the basic grinning face emoji: 😀 I have definitely noticed the difference between the edit box and channel windows yeah. I suspect that the emoji is not present in the font and Wine would be having issues supporting either the fallback from mIRC or even the built-in Windows' one (for example, editbox are drawn and handled by Windows, a channel window is handled by mIRC, often leading to huge difference in appearance between editboxes and channel windows) Which emoji are you talking about and which font are you talking about? Specifying your OS is also relevant because different OS have different font file/version for a given font. I do believe you have no idea if the character/glyph/emoji you're talking about is present in the font you're using or not, and because mIRC isn't the only program to do this, it can be tricky to find out if the font has the character or not. This often leads them to think the font they are using does have the glyph (at least in the mIRC context) because Windows by itself (but mIRC as well when custom drawing), will use fallback fonts to find a character (glyph), this is done to avoid displaying something else than the correct character, whatever that could be.

Non experienced (with fonts/mirc/Windows) users usually have no idea about which or if their font has a given glyph. If you're using a font which has the glyph you are looking for, then it probably works fine under wine, otherwise wine users wouldn't be too happy.
