This is a Typoblindtext . With it you can see if any letters there are , and how they look. Sometimes one uses words like Hamburgefonts , Rafgenduks or Handgloves to test fonts. Sometimes records that contain all letters of the alphabet - you call this sets »Pangrams«. Very well known is this: The quick brown fox jumps over the lazy old dog. Often foreign-language phrases are installed in Typoblindtexts (AVAIL® and Wefox ™ are testing aussi la kerning) to test the effect in other languages??.
