Hmm, compat32 and Python3 start to get in my way in no funny ways. As David implied already, the encoding dance is necessary for compat32. Since my app is a simple postfix filter, I have no way of controlling, how it is executed. "Of course", it is executed in the POSIX locale (LANG=C), which is, as I have learned now, one of the weakest spots of Python3 itself, when it comes to the default filesystem encoding. Needless to say, my filter acts on regex pattern for subjects, attachments and the like, that contain utf-8 literals. If I read the bugs http://bugs.python.org/issue19846, https://bugs.python.org/issue19847, and a couple of others correctly, there's no way to supply a different filesystem encoding without control of the environment variables. Hence, with Python3, I have three choices: * patch postfix to provide a proper locale * patch Python3 to force a certain locale, if setup is broken, e.g.: http://bugs.python.org/file24064//tmp/filesystem_encoding_utf8.patch * change _all_ filesystem operations to catch UnicodeEncodeError and encode manually, which are a lot. These options are awful. Altogether. Am I missing something (again)?
