# If you see an error like along the lines of "'charmap' codec can't encode
|
|
# character '\u200e' in position 42: character maps to <undefined>" then that
|
|
# means a filename has a Unicode codepoint and the dumb aws Python code is
|
|
# trying to read it using your system's locale, which is very likely not set to
|
|
# use the Windows UTF-8 beta feature. This is an ongoing issue in this tool
|
|
# that goes back to 2013!!! There's no way to fix it using environment
|
|
# variables, at least nothing worked for me. The fix provided by the devs is
|
|
# heavy handed: you change your system locale to use UTF-8... This has
|
|
# consequences though like breaking legacy apps that don't have Unicode support
|
|
# and I'm sure other weird things will happen, such as file corruption. Anyway,
|
|
# if you're getting this charmap error then I suggest changing your system
|
|
# locale, run this again, then switch back to your previous locale. If you
|
|
# don't get the canonical file name then you won't be able to restore it.
|
|
#
|
|
# You can enable the UTF-8 locale with:
|
|
#
|
|
# win+r -> intl.cpl -> Administrative tab -> Change system locale -> Beta: Use Unicode UTF-8 box.
