bug#295: 23.0.60; wrong glyph widths of some Unicode codepoints

[Torsten Bronger]

The sub/superscripts (e.g. ⁴ or ₃) are narrower than the ordinary
characters if using a monospace font (monospace-13 in my case), with
the exceptions of ¹²³.  The same is true at least for the prime
character ′.  The right arrow → and the cubic root ∛ used to have a
"correct" width, but with the recent Emacs, it is too wide (the
cubic root even too tall, too).

Is it sensible at all to report such observations, maybe on a more
systematic/complete basis?
