Font is not recognized as a monospaced font in Fedora 44 & KDE

[sphars]

Just discovered this font, and wanted to try it. Downloaded the latest release (v2.0.0) and installed both IoskeleyMono and IoskeleyMono-Term-NerdFont on my Fedora 44 with KDE system. Font installs fine and shows up in the system picker, however, it is not recognized as a monospaced font.

For example, here is the system font picker (initiated from Settings -> Texts & Fonts -> Fonts, then the picker for Fixed width) that shows that Ioskeley is installed:

And here is the same dialog with the Show only monospaced fonts option checked. Ioskeley is not listed:

This also extends to font pickers in other applications, such as Konsole (default KDE terminal).

Using the command fc-list :mono | awk -F: '{print $2}' | sort -u to show available monospaced fonts also fails to list IoskeleyMono:

Output

 $ fc-list :mono | awk -F: '{print $2}' | sort -u

Regardless, using the font works fine, just have to make sure that the option to list all fonts is selected or manually type the font name.

Thanks for the font!
