Yes it does. You can for some APIs pass a param to force the output to
be in another locale. I don't think the CL client uses those, but the
APIs can do this.
I haven't implemented this for two reasons:
* I don't know how to convert a locale given as a string (e.g.,
"iso-8859-1") into the value needed to pass to the Windows APIs.
* TSVN doesn't use those anyway

Well, to be honest, I simply don't have the energy to deal with that
anymore. So I just kept the patch for TSVN. And with this patch I was
(and still am) absolutely sure that it will get rejected:
* it doesn't work for conversions to/from a charset which is not set as
the current one in the process/thread
* it uses new/delete instead of apr pools to reserve the memory

And I haven't really checked, but there also might be some tabs in there
instead of spaces :)

Yes, I could have done this 'properly' by using apr pools and maybe come
up with some workaround for the non-current locale conversions. But that
would have meant more work for me, with the very high risk that after I
addressed all the concerns of the devs it would still get rejected.

Yes, I don't define APR_HAS_XLATE. If that isn't defined but WIN32 is,
then the windows APIs are used to convert from/to utf8.
