[Python-Dev] Re: PEP 597: Add optional EncodingWarning

2021年2月12日 11:56:19 -0800

Offering encoding="locale" (or open.locale or ... ) instead of a long function 
call using False (locale.getpreferredencoding(False)) seems like a win for 
Explicit is Better Than Implicit. It would then be possible to say "yeah, 
locale really is what I meant". 
Err... unless the charset determination is so tricky that it ends up just 
adding another not-quite-right near-but-not-exact-synonym.
Adding a new Warning subclass, and maybe a new warning type, and maybe a new 
environment variable, and maybe a new launch flag ... these all seem to risk 
just making things more complicated without sufficient gain.
Would a recipe for site-packages be sufficient, or does this need to run too 
early in the bootstrapping process?
