Yes, that was the intent.
And, with NetBSD iconv(1) I have:
% printf '\xe4' | /usr/bin/iconv -f EBCDIC-US -t UTF-8
U
Same here with GNU iconv(1) on Linux.
...while with iconv(1) provided by the `libiconv' package:
% printf '\xe4' | /usr/pkg/bin/iconv -f EBCDIC-US -t UTF-8
/usr/pkg/bin/iconv: conversion from EBCDIC-US unsupported
/usr/pkg/bin/iconv: try '/usr/pkg/bin/iconv -l' to get the list of supported
encodings
% echo $?
1
So, in if GNU iconv(1) is available `$skip_param_value_checks' is
set to 1.
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.
I get the same result as you: U with 0 exit status.
If the exit status is 0 and then, in test-charset context
`$skip_param_value_checks' is 0, what happens if you try (this is
stolen entirely from 'replacement character in parameter value'
test in test-charset):
$ printf "Subject: invalid parameter value charset\nMIME-Version:
1.0\nContent-Type: text/plain; charset*=invalid''%%0Dus-ascii\n" | \
mhshow -file - | cat
Here, I have:
| Subject: invalid parameter value charset
|
| mhshow: Can't convert ?us-ascii to UTF-8
| mhshow: unable to convert character set from ?us-ascii, continuing...
| [ part - text/plain - 0B ]
That was the intent, too. 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.
