.SH INTERNATIONALISATION
Dnsmasq can be compiled to support internationalisation. To do this,
the make targets "all-i18n" and "install-i18n" should be used instead of
the standard targets "all" and "install". When internationalisation
is compiled in, dnsmasq will produce log messages in the local
language and support internationalised domain names (IDN). Domain
names in /etc/hosts, /etc/ethers and /etc/dnsmasq.conf which contain
non-ASCII characters will be translated to the DNS-internal punycode
representation. Note that
dnsmasq determines both the language for messages and the assumed
charset for configuration
files from the LANG environment variable. This should be set to the system
default value by the script which is responsible for starting
dnsmasq. When editing the configuration files, be careful to do so
using only the system-default locale and not user-specific one, since
dnsmasq has no direct way of determining the charset in use, and must
assume that it is the system default.
