Hello ! Did anyone found how to do it ? It would be nice for displaying scores and stuff like that. I couldn't find the option anywhere so I downloaded the UI source code from bitbucket but it seems what I need is buried inside UnityEngine.TextGenerator which seems to be on the native side. TextGenerator.characters has a UICharInfo structure which does have charWidth. That could be forced to the width of max(width(M), width(W), width('00')) (see definition of quadrats in typography). Unfortunately, I could find any setters for that Does anybody have another solution that doesn't involve using boring fonts or render quads manually ?
