Subject: bug#53050: 29.0.50; freetype font drivers reports invalid weight
Date: Thu, 06 Jan 2022 19:54:42 +0800	[thread overview]
Message-ID: <87czl53wql.fsf@yahoo.com> (raw)
In-Reply-To: 87czl53wql.fsf.ref@yahoo.com


Do `M-x set-frame-font RET' on a build using a fontconfig-based font
driver (such as ftcrhb) and hit TAB.  There will be many fonts like
this:

  -1ASC-Liberation Mono-regular-italic-normal-*-*-*-*-*-m-0-iso10646-1
  -1ASC-Liberation Mono-regular-normal-normal-*-*-*-*-*-m-0-iso10646-1

Where the weight specification is `regular'.  The documentation for the
`weight' spec, however, says:

‘:weight’
     Font weight—one of the symbols (from densest to faintest)
     ‘ultra-bold’, ‘extra-bold’, ‘bold’, ‘semi-bold’, ‘normal’,
     ‘semi-light’, ‘light’, ‘extra-light’, or ‘ultra-light’.  On text
     terminals which support variable-brightness text, any weight
     greater than normal is displayed as extra bright, and any weight
     less than normal is displayed as half-bright.

Which doesn't include `regular' as a valid weight.  In Emacs 28, the
same fonts' weight attributes are also simply `normal'.
