Because you can pretty much say the same for build with iconv
enabled, I think that line of argument is futile.  The users do not
have control over platform's iconv (and sysadmin's choice of locale
packages) what charset/encoding can be converted to what other ones.

No, I was trying to point out the total lack of corresponding
warnings in the iconv-enabled build.

After all, if you had to convert between UTF-8 and ISO-2022-JP, the
latter of which your system does not support, whether you use
iconv-disabled build of Git or iconv-enabled build of Git, we pass
the bytestream through, right?  Your patch gives warning for the
former (which is a good starting point if we want to warn "user
expected them to be converted, we didn't" case) but does not do
anything to the latter, even though users of the iconv-disabled
build is more likely to be aware of the potential issue (and are
likely to be willing to accept that) than the ones with
iconv-enabled build that runs on a sysmet that cannot convert the
specific encoding.
