Detailed Description

Currently we use DejaVu fonts for English and some languages as the default font and other fonts for languages not covered by them. this situation causes inconsistent text rendering on applications and desktops, particularly when mixing different character sets.

This change aims to provide better experience and consistent text rendering across more languages by replacing DejaVu with Noto.

The following packages will be installed by default to replace DejaVu's coverage:

• google-noto-sans-vf-fonts
• google-noto-serif-vf-fonts
• google-noto-sans-mono-vf-fonts
• google-noto-sans-arabic-vf-fonts
• google-noto-sans-cherokee-vf-fonts
• google-noto-sans-thaana-vf-fonts
• google-noto-sans-hebrew-vf-fonts
• google-noto-rashi-hebrew-vf-fonts
• google-noto-sans-math-vf-fonts
• google-noto-sans-armenian-vf-fonts
• google-noto-serif-armenian-vf-fonts
• google-noto-sans-canadian-aboriginal-vf-fonts
• google-noto-sans-georgian-vf-fonts
• google-noto-serif-georgian-vf-fonts
• google-noto-sans-khmer-vf-fonts
• google-noto-serif-khmer-vf-fonts
• google-noto-sans-lao-vf-fonts
• google-noto-serif-lao-vf-fonts
• google-noto-serif-gurmukhi-vf-fonts
• google-noto-serif-sinhala-vf-fonts

Benefit to Fedora

We would get better text rendering on applications and desktops.
