"Options->Set Default Font..." (or menu-set-font) font selection menu
doesn't let you select
certain fonts styles, eg. "Source Code Pro ExtraLight" font
(https://github.com/adobe-fonts/source-code-pro). Only "Regular" works.
It complains:
set-face-attribute: Font not available: #<font-spec nil nil Source\
Code\ Pro\ ExtraLight nil nil light nil nil 12.0 nil nil nil ((:name .
"Source Code Pro ExtraLight-12:light") (user-spec . "Source Code Pro
ExtraLight-12:light"))>
I cannot reproduced this. I tried both Emacs 24.5 and the latest RC
of Emacs 25.1, on Windows 7, and both allowed me to select any style
of this font family.
The fonts come in a large archive, with many different variants (OTF,
TTF, WOFF, WOFF2, etc.). Which ones did you install? I installed the
ones in the TTF directory.
Also, please try this in "emacs -Q", perhaps some of your
customizations get in the way.
Thanks.
