Xpra info failing with traceback

[J. Max Mena]

Sorry, I have another "feature broken with traceback" ticket. As usual, the server is a Fedora 26 trunk r18035 (freshly updated).

When running xpra info I get this traceback:

Exception in thread parse:

This was caused by r18030 which was trying to make unicode play nice with python2 and python3 on the win32 console:

• r18036 fixes this for most platforms (..)
• r18037 makes us ignore the platform's "preferred encoding", which is "cp1252" on my win7 VM and was causing unicode to come out garbled with python3...

What this should allow us to do is use unicode characters anywhere strings are allowed, ie:

python2 /usr/bin/xpra start --session-name="Schrödinger"

Then both python2 and python3 versions should be able to print the session name without errors:

python2 /usr/bin/xpra id

python3 /usr/bin/xpra id

This should also fix "xpra info" errors when some of the window metadata contains unicode. (ie: running applications with a non-english locale)

Some entertaining read on the subject:

• ​Changing default encoding of Python?: sys.setdefaultencoding('UTF8') considered harmful
• ​Why should we NOT use sys.setdefaultencoding(“utf-8”) in a py script?

Noted, closing.
