OK, the reason is that EBCDIC-US isn't known. Does /usr/pkg/bin/iconv -l list another suitable character encoding, such as EBCDIC-UK? The test uses an EBCDIC encoding to show that it really does a non-trivial translation, but it could use a different one. > I'm now curious if apart FreeBSD and NetBSD with `libiconv' package > installed what happens on other platforms, just checking the exit status > of: > > $ printf '\xe4' | iconv -f EBCDIC-US -t UTF-8 > > will be probably enough.

Based on Ralph's (re-?)discovery that the charset name gets normalised by GNU iconv, I see now why the test behaved differently on the FreeBSD 10 buildbot. I reworked test-charset to reflect that. It still uses EBCDIC-US. David -- Nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
