Using UTF-8 encodings for SVN commit message

[Anthony Liguori <aliguori-NZpS4cJIG2HvQtjrzfazuQ@public.gmane.org>]

Howdy,

I have a bit of an odd request.  I've been using tailor to mirror KVM in 
mercurial which is my preferred SCM.  This has worked quite well up 
until sometime in December when tailor started throwing errors.

I finally got around to looking into it and discovered the source of the 
problem.  It seems that on December 26th, Avi committed a patch from 
Yoshimi Ichiyanagi "kvm: initialize kvm_arch_ops in kvm_init()".

The problem is that the commit message (which was likely copy-pasted 
from an email) contains a character that is neither ASCII nor is it 
UTF-8.  SVN commit messages should be encoded in UTF-8.  The reason for 
this is that SVN allows exporting information about the repository in 
XML which is marked as UTF-8 encoded.

If commit messages aren't valid UTF-8, SVN generates invalid XML.  While 
SVN should probably generate an error when committing non-UTF8 messages, 
we shouldn't be doing it in the first place.

Is there any way to fix this?  I'm going to try to find a way to hack 
around it in tailor but I suspect this will break other SVN tools too.

If nothing else, I was hoping we could be a bit more careful about this 
in the future (if that's at all possible).

Thanks!

Regards,

Anthony Liguori
