Hello!

Is it possible to set a locale for the lexical_cast? It looks like that it is only possible to convert english/us numbers to a string?

No, it has been suggested several times and has always been rejected. (The main reason seem to be that anything ending with _cast should only take a single argument) However, as long as you are dealing with user input/output is not a big deal since locale_cast always use the current locale which I assume you set at program startup. Problems start when you need to convert things with another locale as well (e.g. SQL statements or csv files). There is a string_convert library in the vault which allows you to specify locale and formatting etc but it is very poorly documented and might not work with all compilers.
