# In general it is very difficult to do this correctly.

|
# We may pull information from environment variables, and what encoding that is
|
|
# in is anyone's guess. Any information we request directly from the file
|
|
# system will be in filesystemencoding, and (parts of) paths that we write in
|
|
# this source code will be in whatever encoding the source is in. (I hereby
|
|
# declare this file to be UTF-8 encoded.)
|
|
#
|
|
# To make things more complicated, modern Windows filesystems use UTF-16, but

|
# the API tends to hide this from us.
|
|
#
|
|
# I tried to minimize problems by passing Unicode strings to OS functions as
|
|
# much as possible. Hopefully this makes the function return an Unicode string
|
|
# as well. If not, we get an 8-bit string in filesystemencoding, which we can
|
|
# happily pass to functions that operate on files and directories, so we can
|
|
# just leave it as is. Since these paths are meant to be internal to Gajim and
|
|
# not displayed to the user, Unicode is not really necessary here.
