It appears that the text is no longer monospace when the fonts are mixed and matched Here the example shows a mixture of Fira Code and Consolas for the characters that Fira Code does not support, namely "ʷ" and "ɖ". The characters are a different width than the neighbouring "d". Is there a setting to fix this?
I have tried to search the settings and haven't found anything.
I'm not aware of a way to do this, so I raised a feature-request asking for it: Way to adjust font sizings for when multiple fonts are active #196937. If you'd like to see it get added to the backlog, please give it a thumbs up. You can also subscribe to it to get notified about discussion and progress. Please avoid making noisy comments there like "+1" / "bump".
