Huzzah, and congratulations! :) Regarding the encoding question, I agree with your recommendation with one key amendment to account for the 16-bit console APIs on Windows: * on platforms with 8-bit standard streams (e.g. Linux, Mac OS X), build systems SHOULD emit UTF-8 encoded output * on platforms with 16-bit standard streams (e.g. Windows), build systems SHOULD emit UTF-16-LE encoded output * on platforms that offer both, build systems SHOULD use the 16-bit streams to match the default behaviour of CPython 3.6+ * install tools MUST NOT fail the build solely due to improperly encoded output, but are otherwise free to handle the situation as they see fit Folks on Python 3.5 and earlier on Windows may still have problems given that guidance (since that uses the 8-bit stream interfaces with the Windows native encodings by default), but that's also a large part of why CPython's behaviour on Windows was changed in 3.6 :) Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org https://mail.python.org/mailman/listinfo/distutils-sig
