   Remove obsolete _() wrapper crud for internationalization we don't do.
   Figure out where we need utf8 support, and add it.

 Unicode work needed:
 
+Unicode support uses libc multibyte functions if LOCALE_SUPPORT is on
+(in this case, the code will also support many more encodings),
+or uses a limited subset of re-implemented multibyte functions
+which only understand "one byte == one char" and unicode.
+This is useful if you build against uclibc with locale support disabled.
+
+Unicode-dependent applets must call check_unicode_in_env() when they
+begin executing.
+
+Applet code may conditionalize on FEATURE_ASSUME_UNICODE
+in order to use more efficient code if unicode support is not requested.

+Available functions (if you need more, implement them in libbb/unicode.c
+so that they work without LOCALE_SUPPORT too):
