Characters that appear unexpectedly narrow

[timo-suoranta-varjo]

The following characters appear unexpectedly narrow:
‧ U+2027 Hyphenation Point
∘ U+2218 Ring Operator
⋅ U+22C5 Dot Operator
⸱ U+2E31 Word Separator Middle Dot

These characters also appear narrow in any other of the few monospaced fonts that I tried (Courier, Consolas, Cascadia Mono, Lucida Console), so there may be a common reason.

I tested rendering these characters with Visual Studio Code and Windows Notepad. All listed characters appear narrow on both.

What you are seeing are fallback characters, rendered in a different font.
None of the code points you list are supported in Source Code Pro (presumably also not in Consolas etc.):

code point	character	name	supported
U+2027	‧	HYPHENATION POINT	✘
U+2218	∘	RING OPERATOR	✘
U+22C5	⋅	DOT OPERATOR	✘
U+2E31	⸱	WORD SEPARATOR MIDDLE DOT	✘

If you have a use case (with examples) for these characters, you may consider changing this issue to a “please add xxx” request.
Thanks!
