[PATCH] doc: printf: make "java" encoding example more standard

[Pádraig Brady]

Note using iconv(1) rather than recode(1) is not appropriate
for this example, as the required functionality is only
available on libiconv's iconv implementation, which is
not installed on most systems.

* doc/coreutils.texi (printf invocation): Use env rather than
/usr/local/bin for the printf command.  Escape '%' so more robust.
Also use a locale that exists on modern systems.
