Isn't the English (EU) layout close enough? I think it's basically the US layout with a Euro sign somewhere, but the physical key layout should be the same as a regular US keyboard.
Just map the character set you want to the keyboard and start using it. It'll take some getting used to but if you're a touch typist it mostly comes natural. Living in Sweden, using a P50 with a UK layout which I switch between US-intl and Swedish layouts there isn't always that much relation between what's on the keys and what appears on the screen but by now I'm used to it. As a bonus it makes shoulder surfing passwords an exercise in futility...
The "generic" layout names are ISO (European) versus ANSI (US). The ISO Enter key is two keys tall and narrower. ISO also has a shorter left Shift key, which leaves space for an extra key.
Dell has a few models with keyboards that accept both layouts, but in most laptops the "grid" above the keys prevents switching between them, which makes it really annoying if you ever buy one with an ISO layout, hoping to be able to just buy an ANSI keyboard later to replace it...
For starters the return key are different widths, which is a deal breaker if you’re a touchtyper used to wider return keys.
Programming also uses tilde and other symbols that are different between the two.
Overall they’re similar for typing alphabets, but symbols and enter key are different.
