Re: [PATCH - v3] readable error messages on non-ASCII systems

This isn't going to do the whole job, nor is patch #2. If I grep for
'svn_cmdline_printf.*\"' to find where native literal strings are passed to
svn_cmdline_printf, I get 130 hits in trunk, for example:

./subversion/svn/util.c: SVN_ERR(svn_cmdline_printf(pool, _("\nWarning:
./subversion/svn/proplist-cmd.c: SVN_ERR(svn_cmdline_printf(pool,
_("Properties on '%s':\n"), name_local));

So it's not just error messages that are a problem on z/OS. Digging deeper,
I see that the svn ctype functions are hardwired to ASCII. If they called
the equivalent apr ctype functions instead, they should become portable to
EBCDIC. Doing that should change the behavior of
svn_utf__cstring_from_utf8_fuzzy() and produce readable normal messages as
well as the error messages.
