This is a typoblind text. You can use it to see whether all the letters are there and what they look like. Sometimes words like Hamburgefonts, Rafgenduks or Handgloves are used to test fonts. Sometimes sentences that contain all the letters of the alphabet - these sentences are called "pangrams". This one is very well known: The quick brown fox jumps over the lazy old dog.
Foreign-language sentence parts are often incorporated into typoblind texts (AVAIL® and Wefox™ are testing aussi la Kerning) to test the effect in other languages. In Latin, for example, almost every font looks good. Quod erat demonstrandum. Since 1975, most test texts have been missing the numbers, which is why, according to TypoGb.
