Bug#1003213: locales-all: introduce locales-utf8 package?

[Simon McVittie <smcv@debian.org>]

Package: locales-all
Version: 2.33-1
Severity: wishlist

As discussed recently on -devel and previously in #701585, at the moment
Debian users have a choice between two non-ideal locale setups:

* install locales and generate a subset of locale files with locale-gen
  (this is optimal for small systems, but it's difficult for high-level
  UIs like GNOME Settings to present this to users, particularly in a
  non-distro-specific way)

* install locales-all (this costs > 200M but ensures that all locales are
  available)

For "reasonably large" desktop and server systems, I wonder whether it
might be better to generate a subset of locales-all with just the UTF-8
locales that we recommend for general use, and install that by default?

If I'm counting correctly, that would be about 100M, which is perhaps an
acceptable price to pay for language settings being straightforward -
a reasonably complete set of Noto fonts (without CJK) is already more
than half of that.

locales-all could have a Depends on locales-utf8 and contain the remaining
(legacy national character set) locales, if anyone still needs that.

locales-utf8 would probably also be enough for many locale-sensitive
packages' test suites.
