There can never be too much documentation, and for dnsmasq most of the 
required documentation is needed by both packagers and users. The things 
that you identified as missing to be with build targets and variables, 
are probably things that users don't need, if they are using packaged

One of the files in question is /etc/hosts. The format of that is well 
defined, so there's no way to add a charset tag to it. Since it's a 
system-wide configuration file, then the only valid assumption is that 
it uses the system-default locale, I think. When I was doing this work, 
I experimented with non-ascii characters in /etc/hosts. At least with 
gnu libc, the resolver library works fine, but I suspect it may not if 
the locale associated with a process has a different character encoding 
to that used in /etc/hosts.
