I haven't patched the subversion code base but apr-iconv and gettext.
- iconv is patched to _not_ use the APR_ICONV_PATH env variable which
lead to many, many problems due to incompatible c-runtime libs of VC6
and VS.NET
- gettext is patched to use the apr-iconv instead of its own iconv lib.
I don't like the idea of shipping two identical (in functions and
features) libraries.

No. It wouldn't. For the CLI to use the encryption, I would have to
patch the CL client too.

the apr-iconv was patched to not use the APR_ICONV_PATH env variable.
Apr-iconv uses that to find out where the *.so files are located which
it loads and uses to convert between char encodings.
Now, my patch is to get rid of that env variable because it can only
point to _one_ location which means that all clients using this lib must
use the same *.so files. And since those *.so files are not really
compatible, depending on the compiler you used to build them, this lead
to many many problems and crash reports on the mailing list.
And the performance part: apr-iconv read the env variable _every_ time a
char conversion was requested. I now fetch the path to the *.so libs
only once and then keep that in memory, so no need to read the env
variable for every conversion (env variables are read through registry
calls, which are somewhat slow).

Not a good idea. TSVN is not the official Subversion client. And I also
don't have a really big influence on the Subversion people. Or why do
you think I had to patch Subversion myself for the 1.0.x branch?
