+   ISO-8859-* encodings are (optionally) supported.  The internal
    representation of wchar's is assumed to be 31 bit unicode values in
    native endian representation.  Also, the underlying char encoding is
    assumed to match ASCII in the range 0-0x7f.

 locale support
 --------------
 1) The target for support is SUSv3 locale functionality.  While nl_langinfo
    has been extended, similar to glibc, it only returns values for related
    locale entries.
-2) Currently, collation support is being implemented.
+2) Currently, all SUSv3 libc locale functionality should be implemented

 stdio

-1) For printf, %a, %A, and floating point locale-specific grouping are not
-   yet implemented.  Also, conversion of large magnitude floating-point values
-   suffers a loss of precision due to the algorithm used.  The conversion
-   function was written before uClibc had proper semi-numerical macros/functions.
-   This code is slated to be rewritten after the i10n/i18n work is completed.

 2) uClibc's printf is much stricter than glibcs, especially regarding positional
    args.  The entire format string is parsed first and an error is returned if

    sophistication/performace for minimal size.
