[Qemu-devel] [PATCH 0/2] Fix compilation with python-3 if en_US.UTF-8 is unavailable

[Matthias Maier]

Hi,

This patch series,
 - removes the PYTHON_UTF8 workaround introduced in d4e5ec877ca
 - adds a different workaround that avoids the locale problem altogether by
   opening files in binary read/write mode and setting encoding/decoding
   (in utf-8) explicitly

The problem with setting

  LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8

is that the en_US.UTF-8 locale might not be available. In this case setting
above locales results in build errors even though another UTF-8 locale was
originally set [1].

We propose a different approach to fix the locale dependent encode/decode
problem in common.py utilizing the binary read/write mode [2,3] and
decode/encode with explicit UTF-8 encoding arguments [4].

This approach is preferred over the fix in commit d4e5ec877ca because it is
(a) locale independent, and (b) does not depend on the en_US.UTF_8 locale
to be available.

Best,
Matthias and Arfrever
