However, suppose your program needs to create a file with a name based on a database information. Your database is UTF-8. How do you translate that UTF-8 data into a filepath? This is the problem we got in Haskell. We have a nice coding-agnostic String datatype, but we don't know how to create a file with this very name. It is simple — you recode from (database | "network server" | file) encoding to the current locale. Recoding is indeed very simple. You know the source coding (e.g. your database is in UTF-8). But how do you discover the target coding? How can you find out that this system uses ISO8859-1, while this other one uses UTF-16, while...?
See the problem now? :) No! The target encoding is the current locale. It is a no-brainer to find it. Use your Unix. $ man setlocale $ locale
