# We use utf_8 encoding everywhere. Previously, we used
# sys.getfilesystemencoding() for the 'merge' encoding, but that had
# various problems:
#
# 1) If the locale is ever changed then it can cause orphan files due
# to changed character set translation.
#
# 2) Ebuilds typically install files with utf_8 encoded file names,
# and then portage would be forced to rename those files to match
# sys.getfilesystemencoding(), possibly breaking things.
#
# 3) Automatic translation between encodings can lead to nonsensical
# file names when the source encoding is unknown by portage.
#
# 4) It's inconvenient for ebuilds to convert the encodings of file
# names to match the current locale, and upstreams typically encode
# file names with utf_8 encoding.
#
# So, instead of relying on sys.getfilesystemencoding(), we avoid the above
# problems by using a constant utf_8 'merge' encoding for all locales, as
# discussed in bug #382199 and bug #381509.
