We have an abbreviation called “LE”. When you use normal words like “Alle” or “Leben”, highlighting is off, as it is set to only highlight full words. However, if there are german special characters like ä,ö,ü,ß in front or behind of “LE”, and it is on the start or end of the word, it will be highlighted.
Example word: “Kanäle”. Many common endings in german are abbreviations people like to use, and we sure have many umlauts.
