Hi Emacs,
I tried to use the medium weight of IBM Plex Mono font on Windows 10,
and find that `set-face-attribute` can not make it works as expectd.
Steps to reproduce:
1. Download IBM Plex Mono font by this link:
https://github.com/IBM/plex/releases/download/v6.3.0/TrueType.zip
2. Unzip the TrueType.zip and install the IBM Plex Mono
3. Start Emacs with `emacs -Q`
4. In the `*scratch*` buffer, eval the code below:
```
(set-face-attribute 'default nil :font (format
"%s:pixelsize=%d:weight=medium" "IBM Plex Mono" 20))
```
5. `M-x describe-char`, will get info about font as below:
harfbuzz:-outline-IBM Plex Mono-regular-normal-normal-mono-20-*-*-*-c-*-iso8859-1 (#x03)
And you can see the regular weight is used instead.
expectd: return the medium weight of font.
The workaround recently I used:
```
(set-face-attribute 'default nil :font (format
"%s:pixelsize=%d:weight=medium" "IBM Plex Mono Medm" 20))
```
`M-x describe-char`, will get info about font as below:
harfbuzz:-outline-IBM Plex Mono Medm-medium-normal-normal-mono-20-*-*-*-c-*-iso8859-1 (#x18)
But use the `IBM Plex Mono Medm` name is not convenient for me, because
I also want to switch to other weights sometimes, such as:
```
(set-face-attribute 'default nil :font (format "%s:pixelsize=%d:weight=regular" "IBM Plex Mono" 20))
(set-face-attribute 'default nil :font (format "%s:pixelsize=%d:weight=bold" "IBM Plex Mono" 20))
```
It would be more consistent If we can use the `IBM Plex Mono` font name
with all font weights.
Meanwhile, I aslo tested `set-face-attribute` on macOS, it works as expected with
the same font setting.
If you need more information, please let me known.

Emacs on MS-Windows doesn't fully support any weights except these 4
standard ones: regular, italic, bold, bold-italic. AFAIU, it is a
limitation of the APIs we use on Windows to enumerate font families.

Yes, those are all aspects of the above limitation. You could
configure the other faces (bold, italic, and bold-italic) explicitly
to use the specific members of this font's family, like you did with
the default face and the medium weight, but the basic problem I
explained above will from time to time rear its ugly head and produce
some unexpected results, when Emacs mutates a font to produce another
weight of the same family.

Thanks for mention the potential risk.
So I will just use the regular weight on Windows if encounter issue.

OK, so I don't think we have anything else to do here, and I'm
therefore closing this bug.
