Subject: eclipse: FTBFS on buster, unmappable character encoding error
Source: eclipse
Version: 3.8.1-11
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Dear Maintainer,

I'm unable to rebuild eclipse from source on Debian Buster.

Reproducer:
  debootstrap buster buster
  systemd-nspawn -D buster
  # add deb-src line to /etc/apt/sources.list
  apt-get update
  apt-get build-dep eclipse
  apt-get source eclipse
  cd eclipse-*
  dpkg-buildpackage -us -uc .

It fails with these messages:

This is with default locale settings:
LANG=
LANGUAGE=
LC_ALL=

I have also tried with LC_ALL values: C, C.UTF-8, en_US, en_US.UTF-8.
None of them succeed although changing the value does mean that it ends
up failing on different strings in different files.
