Putting a min-width property on each of them will achieve that goal,

The goal is not to make the individual characters in U:-- not change
displayed width.  To do that, you'd have to make each character as wide
as the widest glyph in the font, and that will be really ugly.  The goal
is to make the "-" wide enough that you can click it, which is why they
should have a char-spacing property of "one normal character".

How bad would it look if the U:--- thing specifically were fixed width by default, even if the rest of the mode line used a variable-width font? Keeping the individual characters in the U:--- thing from moving around would be very nice. Getting partway there by using :min-width might still be useful for people who *really* want the U:--- thing to be variable-width, but it seems worse than being able to rely[1] on each character staying the same size (and in the same spot).

[1] Well, mostly rely. Some stuff like setting an input method will push the U:--- thing to the right, but that's due to adding all-new characters to the U:--- thing, so I don't see an easy way to avoid that.
