issue #1796

Hi dev,

I am busy on a fix for issue
#1796: defective or malicious client can corrupt repository log messages
and would like to validate that property values are good UTF8.

There is a private function in subversion/libsvn_subr/utf.c:

check_utf8(const char *data, apr_size_t len, apr_pool_t *pool)

All of the *public* methods in subversion/include/svn_utf.h produce new
data. I just need a validation.

Is it ok to publish check_utf8 in subversion/include/svn_utf.h? Is that
"just another fix" or does it have release implications? And how would I
go about it; it would probably have to be called svn_utf_check_utf8... ?

Thanks
Neels
