I think personally I'm coming round to the "always locale" point of view. We already have no cross-platform consistency for text files because of the lf vs cr/lf issue and we have no cross-implementation consistency.
I'm leaning in the same direction.
This has swung me too.
Let me be contrary, then: The "always locale" idea depends, as I understand it, on some relatively global setting. And, especially in the context of functional programming, global things dont strike me as particularly appropriate. This particular global thing also has the wonderful property of being modifiable. So it is actually a global variable.Some years ago, I had a hard time because some program that I hadn't written, but had to call from my program, occasionally changed the locale setting when called. The problem turned out, after much and exasperating work, to be that this changed the behaviour of sprintf: In Denmark we use commas for decimal points. I know that we are not supposed to discuss a new and marvellous IO library on this thread, but let me mention what I would consider a very valuable property of this new library that I believe may affect what we do now to clean up the present affair: I would very much like to be able to specify the desired encoding myself, as others have mentioned, at some level of using this new library. So that the present library in principle could be implemented on top of this by specifying any desirable encoding used, including using the current locale setting or utf-8 or letting the encoding depend on the device or whatever one prefers. So although my favorite choice at this moment is "always utf-8", I am much more concerned that the choice that we make does not exclude the possibility of creating this new and wonderful IO library that can be used easily to support the behaviour of the existing library (in whatever form it is changed into as a result of the present discussion).
