The Universe project uses Google Noto fonts as much as possible. As the Noto project page says:
The name is also short for "no tofu", as the project aims to eliminate 'tofu': blank rectangles shown when no font is available for your text.
According to the Universe Statistic page UCD 14.0.0, there are 144,762 "used" codepoints. This breaks down as follows when you include "unused" codepoints such as "private", "surrogate" and "noncharacter":
Kind | Criteria | Codepoints |
format | gc is "Cf", "Zl" or "Zp" | 165 |
control | gc is "Cc" | 65 |
private | gc is "Co" | 137,468 |
surrogate | gc is "Cs" | 2,048 |
noncharacter | gc is "Cn" | 66 |
modifier | gc is "Mc", "Me" or "Mn" | 2,408 |
emoji | EPres is "Y" | 1,185 |
graphic | otherwise | 140,939 |
Total | 284,344 |
Note that this "Kind" classification is slightly more fine-grained than Unicode's "basic type" but less so than "general category". Also note that the codepoints classified as "private", "surrogate" and "noncharacter" are fixed and will not change in subsequent Unicode versions.
This still leaves a great many codepoints that need to be rendered. The relationship between Unicode codepoints and character glyphs within a font is non-trivial, to say the least; but it can be useful, in a character browser, to render an "archetype" glyph of each codepoint for illustrative purposes.
In Universe, each "used" codepoint has a 32-by-32 pixel bitmap glyph. The aim is to use Google Noto fonts wherever possible to construct these bitmaps, because:
- Noto fonts are "free and open source".
- Their codepoint coverage is relatively good.
- They try to adhere to a consistent look and feel.
Consequently, I named the set of bitmap glyphs "Notoverse". One can think of Notoverse as an alternative to GNU's Unifont initiative, except:
- The glyphs are 32-by-32, not 16-by-16.
- The glyphs are 24-bit RGB, not 1-bit monochrome.
- There is full Unicode 14.0.0 coverage.
The construction of the Notoverse glyphs was tedious and exhausting. I now know why so many similar projects run out of steam. The final breakdown of sources for each of the 144,762 glyphs is as follows:
- Hanazono: 58,118
- Google Noto (CJK): 43,937
- Google Noto (non-CJK): 34,225
- GlyphWiki: 4,948
- r12a.io UniView: 1,022
- BabelStone Khitan: 470
- Scraped from Unicode code charts: 346
- Manually constructed (including some Noto Emoji): 1,696
It turns out that Noto contributes to about 54% of the glyphs; more if we include the glyphs manually constructed from Noto elements.

I hope I haven't trodden on anyone's toes by using their fonts in this way. The individual glyphs are down-sampled to 32-by-32 pixels and used for illustrative purposes only. I trust you'll agree that's "fair use".
So, it looks like we're still a long way from getting a pan-Unicode font, or even a set of fonts that achieve the same goal.
For completeness, here's a list of attempts at providing good Unicode coverage:
- Lucida Unicode, Microsoft, 1993
- Everson Mono, Michael Everson, 1995
- Code2000 et al, James Kass, 1998-2008
- GNU Unifont, 1998-
- GNU FreeFont, 2002-
- GlyphWiki, 2006-
- Google Noto, 2012-
