Domain names (such as lempereur.com) never contain apostrophes or accents. This is not a "spelling error" in the traditional sense, but rather a technical simplification mandated by DNS rules.
Why no apostrophes or accents?
Standard DNS: The Domain Name System only accepts basic ASCII characters (a–z, 0–9, and hyphens).
Universal compatibility: By removing characters like ', é, or ç, it is ensured that the domain will work everywhere, regardless of the browser or server being used.
Visual simplification: Writing "lempereur.com" is simpler and helps prevent typing errors.
