  -- This scan pattern aims to correct properties to:
  --  * keep consistency between RedHatMono and RedHatMono-Italic
  --  * provide single family name e.g. Red Hat Mono
  --  * provide single familylang because of the above
  --  * provide single style name e.g. like :family=Red Hat Mono:style=Light
  --    but :family=Red Hat Mono Light:style=Regular
  --  * provide single stylelang because of the above
  --  * set different family name of the variable font pattern to avoid conflict
