fonts-noto-mono 20200103-3 (amd64 binary) in ubuntu focal

 Noto is a collection of font families,
 each visually harmonized across scripts.
 .
 This package contains Noto Mono font family,
 formerly known as Droid Mono.
 Beware that Noto Mono has a much smaller repertoire
 than Noto Sans or Noto Serif.
 .
 The name "Noto" is short for "No Tofu",
 describing the aim of covering all living Unicode scripts.
 .
 Tofu (豆腐) is Japanese jargon
 for unicode replacement character "�" (U+FFFD)
 often displayed as replacement for unassigned or unknown characters.
