There is a proposal to use Noto as an universal default font to provide a wide range of Unicode characters.

The Noto font becomes popular notably because it is the default on Android, but also on many websites for correct support of mulinigual contents. Many scripts don't have relaiable fonts that work across browsers and OSes. Noto provides this support.
... Adding this would allow more reliable rendering of all multilingual wikis: the fonts would be proposed in the ULS (Universal Language Selector), whose support for many scripts is still very poor (or that only works with some browsers/OSes, or does not support many "extended" letters).
The Noto collection targets the full support of the whole Unicode repertoire (there are some recent additions still not implemetned or a few rare clusters with incorrect ligatures, but these bugs are now rare: the Noto has been made to be usable as the default font for all modern languages on Android, Google sites, instant messaging, or blogs. It is made to allow easy reading on screen. It is then far better than the proprietary Arial font (the free version of Arial is very defective, with only very basic support for Latin, and no support for the IPA).
This collection would be very beneficial for all wikis (notably in Wiktionnary) or on Commons for multilingual descriptions. It does not matter if those fonts are used or not in SVG, but they are usable at any time (and for many scripts, only the Noto offers the sufficient support).
There are about 80 fonts in this set to cover all scripts, styles and weights. These fonts line up correctly (unlike most of the non-Latin fonts currently proposed in ULS that have incorrect metrics).
