I have called in my init file

(set-face-attribute 'default nil :height 160 :weight 'ultra-bold)

But (princ (face-attribute 'default :weight)) gives bold.

Please use `M-x report-emacs-bug' when reporting bugs so that we can see
the information about your Emacs build and OS.

Does the font you use have an ultra-bold variation?  Very few fonts have
that weight (but many have the "black" weight, which is heavier).

Now that you mention it, I do not know exactly what font emacs is using.
I have modus-themes activated.  Are there monospace fonts which go to
ultra-bold?  I do not know whether emacs should report about whether
a weight setup fails for the font being used.

I have no such fonts.  But Sauce Code Pro, for instance, has a Black
variation, which is heavier than ultra-bold.

`C-u C-x =' will tell you what font you're using.

Emacs chooses the nearest variation it can find -- it's very common to
not have exactly the variety requested installed, so if Emacs were to
complain about this, it'd be a lot of noise.

Is there an easy way to find a font supporting some weight attribute.  Currently,
it is quite difficult to know what font one can use.

> `C-u C-x =' will tell you what font you're using.

I just get "point=146 of 145 (EOB) column=0"

Point has to "see" a character for that command to give information
about it, so execute it with point not at the end of the buffer
(including an empty buffer).

It is very confusing.  I loaded a random elisp file and run the command in the middle of the buffer
to get

Put the cursor on a character that has a visible glyph.  You have put
it on a newline, which leaves no trace on display, so you get "no
font" for that.

font" for that.

Now I understand what I have to do.  I went on a word and I get the
font name when I execute the command C-u C-x =

Is there a way emacs can list fonts that closely match some attribute
like ultra-bold.  Deos emacs know the list of fonts one could use?

We don't have such a command, but it could be written if needed.

However, you should really use the dedicated font tools for exploring
the fonts on your system, and Emacs is not such a tool.

> Deos emacs know the list of fonts one could use?

It does, but only in general.

Could emacs describe (with a few examples) some good tools to help users define
the font they would want to use.

So this doesn't seem to be a bug in Emacs, and I'm therefore closing
this bug report.
