Package: bind9-host
Version: 1:9.11.5.P4+dfsg-5.1+deb10u1
Severity: normal
Dear Maintainer,
Since buster, it seems that host insists in outputing a decoded version
of IDN domain names, and if the locale does not support it, it fails:
schaefer@virtual:~$ env LC_CTYPE=C host xn--linux-neuchtel-lhb.ch
host: Cannot represent 'xn--linux-neuchtel-lhb.ch.' in the current locale
(string encoding error), use +noidnout or a different locale
However, the suggested option +nodinout does not work.
Then the manpage says:
> IDN SUPPORT
>If host has been built with IDN (internationalized domain name)
> support, it can accept and display non-ASCII domain names. host
> appropriately converts character encoding of domain
>name before sending a request to DNS server or displaying a reply from
> the server. If you'd like to turn off the IDN support for some reason,
> defines the IDN_DISABLE environment
>variable. The IDN support is disabled if the variable is set when host
> runs.
However:
schaefer@virtual:~$ env LC_CTYPE=C IDN_DISABLE=1 host
xn--linux-neuchtel-lhb.ch localhost
host: Cannot represent 'xn--linux-neuchtel-lhb.ch.' in the current locale
(string encoding error), use +noidnout or a different locale
the only partial workaround I know is to change the locale, e.g.:
schaefer@virtual:~$ env LC_CTYPE=fr_CH.iso-8859-1 IDN_DISABLE=1 host
xn--linux-neuchtel-lhb.ch localhost
But then you don't get the xn-- but you get the diacrictic version in the
specified locale:
linux-neuchâtel.ch has address 46.140.72.222
it would be nice to have a working way of disabling this new host behaviour.
Have a nice day.
